CHAPTER 5 ° METER RESPONSE FACTORS (S,l ENERGE RESPONSE Ts, if D} is a dose reading for radiation of a given onerey | ky; is the normalizing factor for that energy,. then: kyD4 = fyD_ ee . ane Wheres f; = the fraction with the given energy of the total true dose D. Hence: Solving for Ds pis Doj=0y fh se 2 ee 4. ry f (5.2) The f4 may be taken from the dose-energy distributions in Chapter lk and the k, from Figure 5,1, which is a plot of the response factors found for tite earlier model of the AN/PDR=394, then called the AN/PUKe T1B (Reference 10), This is believed to be essentially identical in its response to the later models, For the spectrum used in the Refer= ence 16 calculations, the total response factor was found to be 1.9h. This value was uséd in the dose calculations of that report, For the spectra show in the Figures 4.1 to 4.3, the total energy response factors for all energies above 20 kev were found to be as given in Table 5.1, The value of 1,12 for the H+ 5.2 day spectrua of Shot 1 (Figure 4.3) is used in the revised dose calculations of this report, since this spectrum represents the best data, Fn Re ea Rhea ee a Ue ate ogeeat PMgt . a vals and weighting each response factor by the fraction of totak air-dose in that interval, a total response factor is obtained, ~°.°°4 BS The response of the survey meter to the spectra calculated in Chapter 4 was evaluated in terns of a set of normalizing factors, one - for each energy interval in the spectrum, 2y summing over the intere.7
