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