Calculation of Dose Rates
The dose rate, d, due to transit radiation, is calculated by
means of the expression,
d= k I r/hr
(17-5)
where k = 1.703 x 1076 r/hr per Mev/cm@-sec, a constant that includes
the enercy-absorption coefficient, By (assumed to be
3.35 x 10°72
cm] average ror radiation of energy
from 100 Kev
to 2 Mev), and constants for converting Mev/em) sec to r/hr
