A patient receives 4.2 × 10³ mrads of iodine-131, which emits β-particles. If the factor that adjusts for biological damage is 1 for β-particles, how many rems did the patient receive?

Question

Quizplus · Accepted Answer

The dose in rems is calculated by multiplying the dose in rads by the quality factor. Since the quality factor for β-particles is 1, the dose in rems is the same as the dose in rads. Therefore, 4.2 × 10^3 mrads is equal to 4.2 rads, which is approximately 4 rems.
