Chapter 20.3, Problem 20.2CC

Interpretation Introduction

Interpretation:

When internally exposed to 10 rads of alpha, beta and gamma radiation, which form of radiation will cause the maximum damage has to be explained.

Concept introduction:

Units of radiation:

Curie

The unit of curie is $\text{Ci}$.

One curie is equal to $\text{3}{\text{.700×10}}^{\text{10}}$ nuclear disintegrations per second.

Rad

A rad is defined as the amount of radiation that deposits ${\text{1×10}}^{\text{-2}}\text{J}$ of energy per kg of tissue.

Rem

A rem is defined as unit of amount of radiation for biological damage; it equals the rad multiplied by comparative biological effectiveness (RBE).
