3 We thank you for purchase of the personal radiation detector of “Polimaster” Before the beginning of operation with the personal radiation detector you should get acquainted with the present manual. ! During the search of radiation sources observe the existing rules of operation with radio active materials and sources, as well as the standards of radiation safety. GENERAL INFORMATION1 The personal radiation detector (hereinafter referred to as the indicator) is intended for searching (detection and localization) of radio active (and nuclear materials)2 by means of the analysis of the counting speed of impulses delivered from the detector outlet at registration of gamma (and neutron)2 radiation with indication on a LCD: - the average counting speed of gamma radiation; - the average counting speed of neutron radiation средней скорости счета нейтронного излучения (in the devices having the detector of neutron radiation2); - power of the ambient equivalent of a dose of gamma radiations H•*(10) along the line 137Cs in the collimated radiation (hereinafter referred to as “MED”). The indicator is not a meter. The indicator can be operated both in premises and in the open air. The indicator can be used by a wide circle of consumers, who are by their mode of activities related to detection and localization of sources of the ionizing emissions. The indicator is made as an explosion-proof model. The indicator relates to the explosion-proof electric equipment of group II, sub-group IIC. By the level of explosion protection the indicator relates to the especially explosion-proof electrical equipment and is intended for the use in potentially explosion-proof environments (zone 0). The type of indicator explosion protection is “the sparkle-proof electric circuit ia”. The history of indicator operation is retained in the power-independent storage and can be transferred to a personal computer (PC) via the infra-red (IR) communication channel. 1 In the process of indicator manufacture amendments may be entered to the electric circuit, construction, external execution and software, which do not influence the technical and metrological specifications and, therefore, not reflected in the present manual. 2 РМ1703GNO, РМ1703GNA, РМ1703GNB • РМ 1703М-О • РМ 1703МА • РМ 1703МВ • РМ 1703GNО • РМ 1703GNА • РМ 1703GNВ • РМ 1703М-О1 • РМ 1703М-О1A

9 CLAMP INSTALLATION AND REMOVAL A removable clamp is provided to the indicator for wearing at the waist belt. The clamp may be removed with the aid of a screw driver, as shown in fig.1a. The clamp is installed according to fig. 1б. By an individual order the indicator may be provided with a protecting housing made of synthetic cloth , also providing possibility of wearing at the waist belt. When the protecting housing is used, the clamp is recommended to be removed. а) b) Figure 1 INSTALLATION AND REPLACEMENT OF POWER SUPPLY CELL The indicator is supplied without a supply cell installed. For installation of the supply cell a cover of the supply section is to be unscrewed (11) (figure 2) with the aid of a special spanner included to the supply set; to be installed to the supply cell by observing polarity (the cell electrode marked with "+", must be directed inside the indicator); the cover of the supply section is to be restored. When the supply cell is installed the indicator is automatically switched on. During switching on and during operation of the indicator periodic control is effected of voltage in the supply cell. If the voltage becomes lower than 1,1 V, a mark “ ” is induced in the left lower part of the LCD, and a light and sound (and/or vibrating) signal is given). In this case the supply cell should be replaced. Note – After appearance of a discharge symbol on the LCD the device retains workability for at least 8 hours (with the normal background level). The user may disconnect the indicator of the supply cell discharge for approximately 30 minutes by a short pressing the MODE button. Being so, signaling by operation thresholds will be switched on. CONTROL BUTTONS. INDICATION AT LCD Two push buttons for the device control are located on the front panel of the indicator: (MODE) and (LIGHT) , a liquid crystal display (LCD), a window of the IR transmitter-receiver, a light diode (LED), figure 2.

In case of the indicator operation at temperature below minus 15 °°°°С normal operation of the LCD is not guaranteed. In this case only sound or vibrating indicators should be used as the source detecting indicator. When the indicator returns to the conditions with the temperature above minus 15°°°°С the normal operation of the LCD is restored. INDICATOR SWITCHING ON/OFF For switching the indicator ON in the process of operation the MODE button should be pressed. Immediately after switching on the LCD illumination must be switched on and all LCD segments must be illuminated at the same time approximately for 1 s signaling (sound and/or vibrating) must be switched on, the device must be shifted to the testing mode. In the testing mode a number of the software version (P-1.4) is is indicated at the LCD for several seconds. After completion of the tests the indicator must be shifted to the calibration mode by the background level (except for devices having the search mode "0-9"), the analogue scale is indicated on LCD with the number of segments increased in time, as well as the “САL” message. After calibration completion the indicator must be shifted to the working mode in accordance with the order chart (see attachment A). The indicator is ready for operation. For switching off the indicator a LIGHT button is to be pressed and kept for more than 5 s. Being so, the "OFF" appears. Attention! The indicator is automatically switched off (“OFF” is indicated at the LCD) after reading the indicator operation history in the mode of communication with a PC). OPERATION MODES Operation modes included by the manufacturer in the given indicator modification comply with the order chart (see attachment А). The indicator provides the following operation modes: • the testing mode; • the calibration mode by the background level; • the searching mode (indication of the average count speed, s-1); • the mode of MED measurement; • the mode of MED measurement along with the search function; • the searching mode "0-9" (indication of digits 0-9); • the mode of gamma registration (only for РМ1703М-О1) • the mode of indication of the average count speed of gamma radiation over the time of accumulation (only for РМ1703М-О1) 2 РМ1703GNO, РМ1703GNA, РМ1703GNB
12 • the mode of registration of neutrons21 • the mode of indication of the average count of neutrons over the accumulation time2 • the mode of fast switching of sound and vibrating signaling • the mode of settings:  setting the n factor of gamma channel  setting the n factor of neutron channel  setting the threshold by MED for the searching mode "0-9"  setting the threshold of neutrons count for the searching mode "0-9" • the mode of indication settings:  selection of the sound and/or vibrating indication;  setting the sound volume of the indication; • communication mode with PC via IR channel. • Communication mode by radio channel with Pocket PC (РМ1703MB, РМ1703GNB); TESTING MODE The device enters this mode just after switching on. Before the beginning of the testing process the indication (sound and/or vibrating) is switched on approximately by 1 s. All marks, segments and pointers must be indicated on the LCD. Then on the LCD a number of the software version (P-1.4) is indicated on the LCD for several seconds. In the testing mode all required tests are fulfilled. Initially, the battery discharge level is tested. “bAtt” is indicated on the LCD, as well as quantity of segments of the analogue scale which corresponds to the battery discharge level. Then the “test” message is indicated and the reducing analogue scale. Tests are performed. The time to completion of the test is displayed in relative units on the analogue scale in the form of the reducing number of the indicated segments. After the test completion the device is shifted to the calibration mode by the background level. The analogue scale is indicated on the LCD with the number of segments increasing in time, as well as the message “САL”3. CALIBRATION MODE BY BACKGROUND LEVEL32 The indicator enters this mode automatically after completion of the testing mode, and being so, “CAL” message is indicated on the LCD In the calibration mode the analysis of the background level of gamma (and neutron) emission is carried out. Attention! Find below the principles of operation of the device gamma channel. Functioning of the neutron channel2 is subordinate to a more complicated operation algorithm and is not shown in details in the present manual. The processor counts the number of impulses passed from the detection block over the preset calibration time, and the time is indicated on the analogue scale in relative units from the calibration beginning in the form of increasing number of the indicated segments. In case of recalibration of the indicator by the user during operation the recalibration time may automatically be reduced along with growth of the background level, when calibration is fulfilled. 2 РМ1703GNO, РМ1703GNA, РМ1703GNB 3 The said mode in unavailable in indicators with the switched on SERCHING MODE "0-9"
13 The processor counts the value of the gamma channel operation threshold Operation threshold = N + n * N N – average speed of counting impulses over the calibration time n – number of mean square deviations ( n factor of the gamma channel). n factor changes the value of the operation threshold (the minimum detection level), the less n factor, the less threshold value is and the higher indicator sensitivity is. n factor is set by the user in the mode of settings, if this is permitted in the communication mode with PC by the user-administrator (the manufacturer sets the value of n factor equal to 5,3). The range of factor setting is equal from 1 to 9,9 with discreteness 0,1. For recalibration of the indicator by the background level the MODE button should be pressed (to be kept pressed for more than 2 s), until “CAL” message is indicated on the LCD, then the push button should be released. The analogue scale will also be indicated on the LCD along with the number of segments increasing in time. The automatic calibration function may be switched on in the mode of communication with the PC. Automatic calibration makes it possible to automatically retain the high sensitivity at reduction of the background level and avoid false operations with its slow increase. After calibration completion the indicator is automatically shifted to the operating mode in accordance with the chart of orders (see attachment А). SEARCHING MODE. DETECTION AND LOCALIZATION OF SOURCES OF GAMMA AND NEUTRON RADIATIONS. Being in the searching mode the indicator shows the speed of counts of the gamma channel in the LCD upper line, s-1. The following is indicated in the lower line: РМ 1703М-О1 РМ 1703М-О1А РМ 1703М-О РМ 1703МА РМ 1703МВ • the average statistical indication error of the average count of gamma radiation in per cents; РМ 1703GNО РМ 1703GNА РМ 1703GNВ • the average speed of count of neutron radiation in s-1; All modifications • If at indicator operation in the searching mode the average speed of count of the gamma channel exceeds the upper limit of indication, "OL" is indicated on the LCD. РМ 1703GNО РМ 1703GNА РМ 1703GNВ • If at indicator operation in the searching mode the average speed of count of the gamma channel exceeds the upper limit of indication, “999" blinking message is indicated on LCD.
14 In this mode the indicator operation is carried out to the following thresholds: 1) The fixed threshold by MED, set up in the communication mode with the PC by the user-administrator; When the installed threshold is exceeded by MED the indicator sends light, sound and/or vibrating signals. Being so single-tone periodical signals are sent with the constant interval and duration 1 s by making it possible for the user to acknowledge indication when threshold by MED is exceeded from the operation threshold. 2) The gamma channel operation threshold (the minimum detection level) calculated in the calibration mode and taking into account the changes in the background level. When the gamma channel threshold is exceeded the indicator light, sound and/or vibrating signals. Being so, frequency of the received signals is constant and is increased along with the exceeded gamma channel operation threshold. The whole range of energies of the indicator gamma radiations is divided into four energy channels. Three channels correspond to areas of interest for low, middle and high energies, and the 4th one – to the whole range of energies of the gamma radiation. The operation threshold is calculated for every channel. The processor counts impulses every 0,25 s by each channel from the detection block, and it keeps the amount of impulses during the counting. Being so, every 0,25 s the number of impulses over the last (new) interval is added to the current amount, and the number of impulses during the first (the oldest) interval is deducted from the sum of impulses (the current average). So, the number of impulses stored in the processor for each channel is renewed every 0,25 s. The current average number of impulses is compared every 0,25 s with operation thresholds for each channel, which are calculated in the calibration mode (clause 2.2.3). If the current average value of the number of impulses by any channel exceeds the threshold value, indication (light, sound and/or vibrating) is switched on. 3) The operation threshold for the neutron channel21 c (The minimum detection level), calculated in the calibration mode and taking into account the changes in the background level. If the operation threshold is exceeded the indicator sends light, sound and/or vibrating signals. Being so, double signals are sent with the permanent interval and duration, what making it possible for the user to find indication when the operation threshold of gamma channel exceeds operation of the neutron channel. In the searching mode the device resolves the problems of detection and localization of sources of gamma and neutron radiation. Detection of sources of gamma and neutron 2 radiation (II) For II detection the device should be located so that the rear side (wherein the clamp is fixed) should be directed to the tested object . The closer the device is placed to the tested object (luggage, a human being, a container, a vehicle, etc) and the slower it travels along the object, detection efficiency is higher. For II detection under conditions when sound signals of the indicator may be not heard (for example, excessive noise) the vibrating and light indicator should be used. One should remember that indicator sensitivity and frequency of false operations depend on: - the preset value of n factor by the gamma channel; - the preset value of n factor by the neutron channel; - the background level calculated by the indicator in the calibration mode by the background level. In case when automatic calibration is switched on in the communication mode with a PC, the indicator will automatically take into account slow changes of the background level and calibrate by a new background level approximately after every ten minutes with the reduction of the background level or after somewhat bigger intervals during increase of the background level. However, automatic calibration will be carried out under conditions of absence of indicator operations or sharp changes of the background level over certain intervals defined by the algorithm. 2 РМ1703GNO, РМ1703GNA, РМ1703GNB
15 It should be borne in mind that in case of false operations the signals (light, sound and/or vibrating) are not systematic, and therefore, they differ from detection signals in case of II availability, with their frequency being constant and increasing as far as approaching to II. In case of II detection or if any information is available about possible II availability, II localization is started. Localization of sources of gamma and neutron21 radiation For II localization the indicator should be kept at the distance of not exceeding 10 cm from the object. The traveling speed in relation to the object shall not exceed 10 cm per second. By approaching II frequency of signals increases. With the switched on sound indication sound signals are heard accompanied with blinking of a red LED. With the switched on vibrating indicator mechanical vibrations are felt inside the indicator (casing trembling) accompanied with a red LED. When the limit frequency of light, sound and/or vibration signals have been reached the further localization becomes impossible without calibration by a new background level. For this purpose, if possible, a MODE button should be pressed without changing the distance to the object, and this is to be retained by appearance of “CAL” message on the LCD. The indicator will calibrate by a new background level, after what II localization can be continued. If necessary, these actions cam be repeated several times up to location of II. During localization of the source of neutron2 or mixed gamma and neutron radiations the sound and vibrating indication can not be used, as the indicator will send signals typical for exceeding the speed threshold of counting the neutron channel without any reaction to source approaching and removing. In this case localization should be visual by observing the readings of count speed (or MED) in the upper line of the LCD (gamma channel) or count speed in the lower line of the LCD (neutron channel). MODE OF MED MEASUREMENT. Staying in the MED measuring mode the device in the upper LCD line indicates the MED of photon radiation Н•*(10), in mcЗv/h. The lower line indicates the average statistical MED indication error in percents. If during device operation in the measuring mode the MED value exceeds the upper limit of the measuring range by more than 1.3, “OL” message is shown on the LCD. MED MEASURING MODE ALONG WITH SEARCHING FUNCTION. Staying in this mode the device in its upper line of LCD induces the photon radiation MED Н•*(10), in mcЗv/h.

The range of threshold setting is equal to 15 – 7777 µR/h (0.15-77.77µSv/h), recommended - 30µR/h (0,3 µSv/h)). The preset searching threshold exceeding by MED is accompanied with light and sound signaling. Mechanical vibrations inside the device (casing trembling) are felt with the switched on vibrating indicator instead of sound signals. Frequency of signals increases by device approaching to the gamma radiation source. 2) The safety threshold – the 2nd threshold by MED, is only set in the mode of communication with a PC by the user administrator. The range of threshold setting is equal to 10 – 7000 µR/h (0.1-70µSv/h), the recommended one – 3mR/h (30 µSv/h)). The light, sound and/or vibrating signals are provided in case of exceeding the safety threshold. Being so, single tone periodical signals are provided with the permanent interval and duration of 1 s what makes it possible for the user to differentiate the indication in case of exceeding the searching threshold by MED from the safety threshold.
