EXPERIMENT TITLE/NUMBER : Radiological Protection and Medical Dosimetry for 



the Skylab Crewman 



PROGRAM/MISSION : Skylab 2, 3, 4 



CLASSIFICATION : Human • 



DISCIPLINE(S) : Radiobiology , Environmental health 



OBJECTIVES : To study radiation exposure in space. 



PROTOCOL : Each crewman wore a passive dosimeter strapped on ankle or wrist. 

 Passive dosimeters were placed in the Orbital Workshop film storage vault. 

 Crewmen reported dosimeter readings daily. • 



EQUIPMENT : Passive dosimeters. 



RESULTS : Personal passive dosimeters detected 1.98 to 7.61 rad/mission. 

 Skin, eye lens and blood forming organ doses were computed from Van Allen Belt 

 dosimeter and electron-proton spectrometer. Dose was related to length of 

 mission: 



Skin: 3-44 to 16.04 rem 



Lens: 2.72 to 1 1.83 rem 



Blood forming organs: 1.68 to 7-32 rem. 



CONCLUSIONS : Dose equivalents for each crewman were well below the threshold 

 of significant clinical effect. A SL crewman could fly a mission comparable 

 to one 84-day SL4 mission per year for 50 years before exceeding career limits 

 for radiation exposure.
