How long will it take for a radiographer to receive a total dose of 50 mR if they are exposed to 100 mR/h?

• A. 10 minutes
• B. 15 minutes
• C. 30 minutes
• D. 60 minutes

Answer: (C)

To determine how long it will take for a radiographer to receive a total dose of 50 mR when exposed to a rate of 100 mR/h, you can use the formula: Time (in hours) = Total dose (in mR) / Dose rate (in mR/h). In this scenario, the total dose is 50 mR and the dose rate is 100 mR/h. By substituting these values into the formula, we get: Time = 50 mR / 100 mR/h = 0.5 hours. To convert hours into minutes, you multiply by 60 minutes/hour: 0.5 hours * 60 minutes/hour = 30 minutes. Therefore, it will take the radiographer 30 minutes to receive a total dose of 50 mR at the exposure rate of 100 mR/h. This correct calculation shows how time and dose are directly proportional, revealing how quickly a specific dose can be received based on the rate of exposure.

To determine how long it will take for a radiographer to receive a total dose of 50 mR when exposed to a rate of 100 mR/h, you can use the formula:

Time (in hours) = Total dose (in mR) / Dose rate (in mR/h).

In this scenario, the total dose is 50 mR and the dose rate is 100 mR/h. By substituting these values into the formula, we get:

Time = 50 mR / 100 mR/h = 0.5 hours.

To convert hours into minutes, you multiply by 60 minutes/hour:

0.5 hours * 60 minutes/hour = 30 minutes.

Therefore, it will take the radiographer 30 minutes to receive a total dose of 50 mR at the exposure rate of 100 mR/h. This correct calculation shows how time and dose are directly proportional, revealing how quickly a specific dose can be received based on the rate of exposure.
