RE: Mass Loading on Air Filter Media

["Bradshaw, Keith" <Keith.Bradshaw@nnc.co.uk>]

Look at

'Rapid monitoring of soil, water and air dusts', Sill C.W. (1995) Health
Physics Vol 69 (1)

'Features associated with alpha spectrometry using infinitely thick
sources', Shiraishi F. et al (1999) -8th symposium on environmental
radiochemical analysis, 23-26 Sep 1998, RSC special pub. no. 234, ISBN
0-85404-734-4.

Have not tried these myself

Personal views only
