Thoron decay chain

WebAsked By : Julie Martin. Radon is a member of the 238U decay chain whereas thoron is a member of the 232Th decay chain. Because radon and thoron are members of different decay chains, their concentrations depend in part on the uranium and thorium levels in local soils and building materials.

WebJan 5, 2015 · Thoron at work: 0,5. Potential alpha energy (of radon progeny and thoron progeny): The total alpha energy ultimately emitted during the decay of radon progeny and thoron progeny through the decay chain, up to but not including 210 Pb for progeny of 222 Rn and up to stable 208 Pb for progeny of 220 Rn. The unit is J (Joule). WebThe equilibrium between the Radon decay rate and Po-218 detector activity is given after about 5 half life times, say 15 Minutes. This time span defines the minimum achievable response time to a Radon concentration step. Now, the decay chain is continued by the both beta emitters Pb-214 and Bi-214 followed by another alpha emitter, the Po-214.
