This is College Physics Answers with Shaun Dychko. A person is undergoing cancer treatment using gamma rays and we are told what the absorbed dose in grays is and we wanna divide that by the relative biological effectiveness to calculate the dose equivalent in sieverts. So we need to lookup in table [32.2] what the relative biological effectiveness of gamma rays are and it's 1. So we have 200 grays divided by 1 giving us 200 sieverts.
