[same as page before previous page:] Using my formula roentgens / hour = (1.25 x (10 exponent -4)) ([top line] ((S)/(S sub m ))) (J sub 0 (J sub 0) = particles / ((cm exponent 2) second) ([top line] ((S)/(S sub m))) mean ratio of specific ionization to minimum. i.e., roentgens = ((1.25 x (10 exponent -4))/3600) ([top line] ((S)/(S sub [m?]))) (((J sub 0 ) delta t) seconds) = (1.25 x (10 exponent -4)) ([top line] ((S)/(S sub m ) (((J sub 0 ) delta t) hours) 32 = ((1.25 x (10 exponent -4))/3600) ([top line]((S)/(S sub m ))) (6 x (10 exponent 8)) 32 = (((60)(1.25))/(36)) ([top line] ((S)/(S sub m ))) ([top line] ((S)/(S sub m ))) = 1.53 (?)
