EXPERIMENT TITLE/NUMBER : Radiation Protection and Instrumentation 



PROGRAM/MISSION : Apollo 



CLASSIFICATION : Human 



DISCIPLINE(S) : Radiobiology , Environmental health 



OBJECTIVES : To study natural and man-made radiation in space and to limit 

 astronaut exposure. 



PROTOCOL : Dosimeters were placed at various locations in garments worn by the 

 crew throughout the mission to determine accurate radiation doses for 

 different parts of the body. 



EQUIPMENT : Van Allen belt dosimeter, nuclear particle detection system, 

 neutron resistant foil, personal radiation dosimeter. 



RESULTS : Personal passive dosimeters detected 0.16 to 0.55 rads/mission on 

 Apollo missions. An exception was on Apollo 14 when the crew was exposed to 

 1.14 rad . 



CONCLUSIONS : Radiation was not an operational problem during the Apollo 

 Program. Doses received by the crewmen of Apollo missions 7 through 17 were 

 small because no major solar-particle events occurred during those missions. 

 Solar-particle releases are random events, and it is possible that flares, 

 with the accompanying energetic nuclear particles might hinder future flights 

 beyond the magnetosphere of the Earth.
