IntroductIon: The Radiation Decay demonstration 1s ca.pable of storing tor one to sixteen di:f't"erent positions; intonstlon as to location ot the posit1on, the radioa.ctiv1 ty intensity level at the positIon, and the time ot the radioactivity intensity reading. This data -.y be entered in IUlY' rando.m order either manua.lly using the typewriter or autoaticaJ.ly using the photo-tape reader. Af'ter entering the time of the atomic explosion that caused the present radioactivity level, the computer will give upon ccmaand; (1) a report o-r all entered positions as to its location, its measured intensity, and the time of Deasuremnt, (2) a report ot any or all entered positions at any given time as to the remaining radiation level and i i l t is dangerous or not, and (3) the time when t.he radiation 1evel will be sate if' 1t is not already sate. The sa.ftey level that is considered sate can be determined in advance by the operator in order to adjust to battle condi tiona. Attention 1s brought to the \lOrd "denonstrationtt in the title of this program. A very accura.te prediction ot intensity levels cannot be determined without additionaJ. information such as weather conditions, wind speed and direction,· type of bomb, previous radiation level before the bomb explosion and more accurate formulas. These omisions were purposely made in order to have a less contusing and f'aster operating demonstration. Under average conditions, the answers produced by the deJD::)nstrat1on should be vi.thin a few- percent of the correct value. The typewriter should be loaded vith 8 inch or vider paper, under the type bin cover should be set to execute "tabs" traI the computer I and the tab stops set as given in the s\DIIl1Bry at the end ot this report. the switch '!'he program descr1t1on starts with an outline ot the -.thes.t1cal theory involved followed by an outline ot each of these ajor sections ot the demonstration: T:J.me ot Explosion, Posi t10n Readings, Position Report, Intens1ty level, Intensity Saftey level, Memory ~, and SUDIlIU'"'Y. 2. P 2. Theory: Radioactivity intensity decays e.xponentaJ.ly from the t1ae ot an atomic explos ion according to the equation: I = intensity at SOlie t1ae after explosion (R) I 0 ~:. intensity at t1ae of explosion (R) t :c t1lle ~roll expos ion (hours) c ~ decay constant =: 0.35 The eOJlpUter could solve this equation using a nor.l Talor series expans ion such as: This solution however would take too .any tenas to give an accurate answer so by using the Salle series expanded about 1nf'1n1 ty instead ot zero gives: A resonable accurate a.nsver is nov possible 'W'1 th just the first 3 tel"ltB. In the exponential equation ~ the value c 1s detera1ned by the radioactive element involved in the explosion. Noral.ly~-.ny ele1lents are involved, each with different values of c and any o't these elements are cOllpletly non-radiating w1th:f.n a period of 1.41 hours. A value ot c that 1s an approx1at1on ot the radiation decq a.:rter an average atoJl1c explosion is 0.35 and values ot t less then 1.40 hours are considered the Salle as t = 1.40 in order to overcc.e the high 1nitial inaccuracy brought about by the very fast decay' elew:nts of the bomb. Subst1 tuting these approxiat1ons into equation g}results in A dropping out and: I = I o [~."'5' 6't + o~ 7. [ I -- rr 4t = ". O.If-~ jr,)rI.r ] + ,.35 A-e «t I. - 7iM.
