A radiation worker not wearing protective apparel spent 10 minutes in an area with an exposure rate of 100 mrem/hour. How much radiation did he receive?

To determine the amount of radiation a worker received while spending time in an area with a specific exposure rate, you can use the relationship between exposure rate, time, and dose received.

In this scenario, the worker was in an area with an exposure rate of 100 mrem/hour for 10 minutes. First, it is essential to convert the time from minutes to hours because the exposure rate is given in terms of hours. There are 60 minutes in an hour, so 10 minutes is equivalent to 10/60 or 1/6 hours.

Now, the dose received can be calculated with the formula:

Dose (mrem) = Exposure Rate (mrem/hour) × Time (hours).

Substituting in the given values:

Dose = 100 mrem/hour × (10/60) hour = 100 mrem/hour × (1/6) hour = 16.67 mrem.

Now, to convert this dose to millisieverts (mSv), we can use the conversion factor that 1 mrem is equal to 0.01 mSv. So, 16.67 mrem would convert to:

16.67 mrem × 0.01 mSv/mrem = 0
