See explanation below.
Work Step by Step
a.
The amount of radiation energy absorbed per body mass in kg is called as rad. Given that 135lb person absorbs 3.3x10^-7 J
The amount absorbed can be calculated as:
(3.3x10^-7J/135 lb)(2.205 lb/kg)(1 rad/ 10^-2 J/kg) = 5.4 x 10^-7 rad
b. We know that 1 rad = 0.01 Gy
(5.4 x 10^-2 J/kg)(0.01 Gy)
= 5.4 x 10^-9 Gy
