An asteroid miner comes across an object of extra terrestrial origin in the asteroid belt. knowing there is a lot of money in this, the miner decides to investigate. he sends a remote probe that reports that the object is radiating gamma rays at 5.6 mgray/hour, fast neutrons at 2.7 mgray/hr, alpha particles at 3.2 mgray/hour, and beta minus particles at 2.5 mgray/hr. the miner dons his spacesuit and investigates the object further for 3 hours.
a) what is the dose equivalent (in sv) for each type of radiation that hits his suit, and
b) what is the total dose equivalent absorbed by the miner?
c) if 0.34 sv is his maximum quarterly dose, for his next spacewalk, how many additional hours can he stay out investigating the object before exceeding is quarterly does?
