Chapter 17, Problem 47E

Interpretation Introduction

Interpretation:

To describe the radiation exposure unit and the amount of the radiation to which an average US (United States) resident is exposed to, in the time period of one year.

Concept Introduction:

Radiations are defined as the electromagnetic waves (wave form of energy), which are emitted as a result of the nuclear fusion and fission. The unit of radiation depends on the basis of the expression of the radioactivity. The exposure of an individual to the radiations can be due to leakage from the nuclear power plant or from the natural cause. Radiation exposure is commonly measured in millisieverts (mSv).

SI units	Historical dosimetry
1 Gray	100 R
1 Sievert	100 rad => 100 rem
10 mGy	1 Roentgen
10 mSv	1 rad => 1 rem
