How is 100 mrem over 60 min calculated for a 10-minute exposure?

The correct answer is focused on understanding the relationship between exposure time, dose, and the unit of measurement used. In this case, the dose rate is given as 100 mrem over 60 minutes. This means that for every 60 minutes of exposure, a person would receive a dose of 100 mrem.

To determine the dose for a 10-minute exposure, the calculation involves finding the dose per minute:

100 mrem / 60 minutes = approximately 1.67 mrem per minute.

Then, to find out the total dose for a 10-minute exposure, multiply the dose per minute by the exposure duration:

1.67 mrem/minute * 10 minutes = 16.67 mrem, which is a rounded value that closely corresponds to 0.17 mSv (since 1 mSv is approximately equal to 100 mrem).

Hence, the calculation leads to a total exposure of around 0.17 mSv for 10 minutes, confirming why this answer is considered correct. Understanding that conversion between units of rem and mSv plays a crucial role in radiological dose measurement helps in grasping this concept more thoroughly.
