The occupational limit for adults is 5 rem; this corresponds to how many sieverts?

Explanation:
Converting radiation dose units is the key idea here. In radiation protection, doses are often given in rem, but the SI unit is the sievert. The relationship is simple: 1 sievert = 100 rem, so 1 rem = 0.01 sievert. With an occupational limit of 5 rem, that converts to 5 × 0.01 Sv = 0.05 Sv. The other numbers would correspond to different rem values: 0.005 Sv equals 0.5 rem, 0.5 Sv equals 50 rem, and 5 Sv equals 500 rem. So 0.05 Sv is the correct conversion.
