Abstract
A method and generator for preparing the radioisotope of lead, .sup.212 Pb, whereby .sup.228 Th, in a closed chamber, is allowed to decay to gaseous .sup.220 Rn which is then readily separated from the thorium and other decay products by diffusing the .sup.220 Rn gas into a second chamber, where it decays to .sup.212 Pb which can then be collected from the second chamber. The .sup.228 Th preferably is amorphous, such as thorium stearate. Collection of .sup.212 Pb occurs in a medium of high and open porosity into which the .sup.220 Rn diffuses so that the decay products recoil into the medium. The .sup.212 Pb can be recovered from this medium by dissolving the medium or by reacting it with an antibody-chelating complex solution to entrap it in the antibody-chelating complex.
