What would be the dose rate for 1 hour if an individual receives 8 mR/hr in 2 minutes?

To determine the dose rate for 1 hour based on the information provided, we first need to understand what is being measured. If an individual receives 8 mR in 2 minutes, we can calculate the dose rate for a full hour by scaling this rate up appropriately.

1. Convert the 2 minutes to hours:

2 minutes is equal to 2/60 hours, which simplifies to 1/30 hours.

2. Given the dose received in that time (8 mR), we can find the dose per hour by setting up a proportional relationship:

If 8 mR is received in 1/30 hours, we need to find out how much would be received in 1 hour.

3. Since there are 30 intervals of 2 minutes in an hour, we can multiply the dose received in 2 minutes by 30:

( 8 mR \times 30 = 240 mR ).

Thus, over the period of one hour, an individual would receive a total of 240 mR. Consequently, the dose rate is 240 mR/hr, confirming that the correct answer is indeed accurate. This method of scaling up the dose rate serves to clarify how
