Question

At a radiologist's workstation, the instantaneous exposure rate through the wall from a chest image receptor is 500 mR/h during exposures of 10 mAs at 100 kV and 100 mA. For 200 exposures per week, what is the approximate maximum exposure in mR at the workstation?

Answer 1

The approximate maximum exposure in mR at the radiologist's workstation is 1000 R/week.

Step-by-step explanation:

The approximate maximum exposure in mR at the radiologist's workstation is 1000 R/week. To calculate the approximate maximum exposure in mR at the radiologist's workstation, we can use the formula:

Exposure = Instantaneous Exposure Rate × Number of Exposures × Exposure Time

Given that the instantaneous exposure rate is 500 mR/h, the number of exposures per week is 200, and the exposure time is 10 mAs:

Exposure = 500 mR/h × 200 exposures/week × 10 mAs = 1,000,000 mR/week = 1000 R/week

Therefore, the approximate maximum exposure in mR at the workstation is 1000 R/week.
