METHOD FOR PRODUCING A SEALED <210> PB- <210> PO ALPHA SOURCE (ALPHA PARTICLE EMITTER) AND APPARATUS THEREOF

摘要

The present invention provides a method for producing a sealed <210 >Pb-<210> Po alpha source (alpha particle emitter) and an apparatus thereof, which can be used as an alpha particle source for a random pulse generator. The method for producing a sealed <210 >Pb- <210 >Po alpha source (alpha particle emitter) includes the steps of: collecting <210 >Pb< >-<210> Po with a <210 >Pb collector using radon collection; precipitating the hydroxides of the collected <210 >Pb- <210 >Po and collecting the precipitates by a polycarbonate (PC) filter; dissolving the <210>Pb-<210> Po hydroxide precipitate to form a <210 >Pb-<210> Po radioactive thin film; and sealing the<210> Pb-<210> Po radioactive thin film for protection.
