A radiation worker is subject to a dose of 150 mrad/h of protons for one 40 h work week. How many times the yearly allowable effective dose did she receive?

150mrad/hr*40= 6rads

This is about 6 times the worked allowed exposure for radiation workers, UNLESS she is pregnant.

To determine how many times the yearly allowable effective dose the radiation worker received, we need to compare her dose to the yearly allowable dose.

First, let's calculate the yearly dose for the radiation worker:
Yearly Dose = Weekly Dose x Number of Work Weeks in a Year

Given:
Weekly Dose = 150 mrad/h
Number of Work Weeks in a Year = 52 weeks

Substituting the values into the formula:
Yearly Dose = 150 mrad/h x 40 h/week x 52 weeks

Now, let's calculate the yearly allowable effective dose. This information typically comes from regulatory agencies or guidelines specific to radiation safety. Assuming an arbitrary value of 5000 mrad/year as the yearly allowable effective dose, we can proceed with the calculation:

Yearly Allowable Effective Dose = 5000 mrad/year

Finally, we can calculate how many times the yearly allowable effective dose the radiation worker received by dividing the yearly dose by the yearly allowable effective dose:

Number of Times = Yearly Dose / Yearly Allowable Effective Dose

Substituting the values into the formula:
Number of Times = (150 mrad/h x 40 h/week x 52 weeks) / 5000 mrad/year

By performing the calculation, you will find the number of times the yearly allowable effective dose the radiation worker received.
