Two workers are exposed to the same radiation source. One approaches an unshielded source to within 5 meters and remains that close for 1 hour. A second worker approaches to within 5 meters behind a shield that attenuates 60% and remains there for 20.0 minutes. What is the ration between the absorbed doses for the two workers?
