Answer to Question #166285 in Physics for Ava Thorburn

Question

What is the energy which is absorbed by a mass weighing 65kg which receives an absorbed dose of 3 μGy?

Answer 1

The energy imparted to matter from any type of radiation can be found as follows:

$$D=\dfrac{E}{m},$$

here, $D$ is the adsorbed dose, $E$ energy absorbed by material of mass $m$.

Then, from this formula we can find the energy absorbed by a mass of 65 kg:

$$E=Dm=3\cdot10^{-6}\ Gy\cdot\dfrac{1\ J}{1\ kg}\cdot65\ kg=1.95\cdot10^{-4}\ J.$$
