	Pa:

	'Determination of natural actinides and plutonium in marine
particulate material', Anderson and Fleer (1982) Analytical Chemistry 54
1142-1147.

	'Radiochemical determination of protactinium-231 in environmental
and biological materials', Sill CW (1978) Analytical Chemistry 50 (11)
1559-1571.

	Never tried them myself!

	For Ac-227, try gamma spec for the Th-227 daughter.
