Thoron progeny working level

The thoron progeny Working Levels for calculation of activity distributions were calculated as ... [Pg.228]

The first sample of the day was counted at 270-285 minutes after sampling in order to allow counting to be completed in the underground working period. Equation (7) was used to calculate the thoron progeny Working Level in this case, with 1(330-345) replaced by 1(270-285). [Pg.228]
