An astronaut in the vacuum of space

Reference no: EM13312957

An astronaut in the vacuum of space is performing maintenance near a small reactor in orbit. Assume you can treat the reactor as a point source. If the astronaut's absorbed dose rate at a distance of 2 m from the reactor is 25 mGy/hr from gamma-rays and 4 mGy/hr from fast neutrons, what is the astronaut's equivalent dose rate in mSv/hr at a distance of 10 m from the reactor assuming the only source of radiation is the reactor?
