Van Allen Radiation Belts

["Richard L. Anderson" <anderson.800@OSU.EDU>]

The excerpt below was taken from the web site listed.





Two studies in this area are those of Letaw et al. and Wilson et al.24 

Letaw et al. put the peak dose rate to the blood-forming organs (BFO) of an 

astronaut in a space suit at about 0.3 Sv/h, whereas Wilson et al. put it 

at approximately 0.15 Sv/h. Letaw et al. also give a worst-case composite 

dose rate of about 0.5 Sv/h. These rates are assumed to apply to the SPE 

zones. The peak dose rate lasted about 8 hours, which gives a total dose of 

between 1.2 Sv and 2.4 Sv, depending on which dose-rate estimate is used.
