If an individual receives a dose rate of 120 mrad/hour for 10 minutes, what total exposure do they receive?

To determine the total exposure an individual receives when exposed to a dose rate, you can use the formula:

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

In this scenario, the dose rate is 120 mrad/hour and the exposure time is 10 minutes. First, convert 10 minutes into hours:

10 minutes ÷ 60 minutes/hour = 1/6 hours.

Next, you can substitute the values into the formula:

Total Exposure = 120 mrad/hour × (1/6 hour) = 120/6 mrad = 20 mrad.

Therefore, the total exposure received by the individual is 20 mrad. This calculation illustrates how the relationship between dose rate and exposure time works to give a specific amount of radiation dose received over a specified period. Understanding this relationship is crucial for ensuring safety and compliance in radiography practices.
