Chapter 42: Q 36 Exercise (page 1237)

A 50 kg laboratory worker is exposed to 20 mJ of beta radiation with RBE = 1.5. What is the dose equivalent in mrem?

Short Answer

Expert verified

Therefore, the dose equivalent in mrem is $60 m r e m$ $60 m r e m$

Step by step solution

01

Given information

A 50 kg laboratory worker is exposed to 20 mJ of beta radiation with RBE = 1.5.

02

Explanation

The dose is given as:

$\frac{20 \times 10^{- 3} J}{50 kg} = 0.0004 Gy$

The dose in Sv is:

$0.0004 \times 1.5 = 0.0006 Sv$

03

Calculations

Hence the dose in mrem is

$0.0006 \times 100 = 0.06 rem = 0.06 \times 1000 = 60 mrem$
