Bone
For total activity - aliquot plated on glass planchet and beta
counted. Standardized against 0.2 gms K2C03 mounted in similar
manner. Self-absorption correction factor applied in each case:
based on self-absorption of activity in tuna muscle and bonito
bone.
Aliquot taken for Sr-90:
represented 10-20 gms wet material.
The special assistance received from J. Alercio, A.
Rodriguez, E. French and I. Whitney was invaluable in the prepara-
tion and analysis of these samples.
