Abstract
A technique for the assay of radium by detection of coincident γ-radiation is evaluated. The sensitivity of various counting modalities is compared. The influence of finite sample size and density is discussed. Interference from other natural radioactivities is investigated and it is shown that a two channel arrangement is sufficient to take this into account.
