Method for producing a sealed 210pb-210po alpha source (alpha particle emitter) and apparatus thereof

摘要

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.
