Abstract
The various methods in use for determining the correction for absorption due to the source mount used in a 4π-counter are discussed, and experiments conducted to test the validity of the correction, arising from these methods, for β emitters of varying end-point energies. The methods all give erroneous corrections for low energy β emitters and possible reasons for the errors introduced by the 'sandwich method' are discussed. An 'absorption curve' type method is proposed which is shown to give more accurate correction factors.Keywords
