Abstract
A random pulse and probability generator (RPG) has been developed utilizing the detection technique of alpha-particles as the random signal source. The collection technique for 222Rn emanated from natural uranium ore was examined for preparing highly pure 210Pb-210Po as an alpha source for RPG. The yield with a trap refrigerated by liquid nitrogen was observed to be above 99% for 222Rn collection. [ABSTRACT FROM AUTHOR]
