BIOSIS COPYRIGHT: BIOL ABS. A previous paper1 reported the application of a method for determining 226Ra by alpha-spectroscopy. This paper presents important improvements which permit the determination of 226 Ra in the presence of large amounts of Ca. The method was applied to the analysis of the 226 Ra and U isotopes in fish samples from the waters of the Grand Canyon. 226Ra ranged from 0.05 Bq kg-1/1.4 pCi kg-1/ to 0.17 Bq k-1 /4.7 pCi kg-1/. 238U values ranged from 0.13 Bq kg-1 /3.5 pCi kg-1/ to 0.52 Bq kg-1 /14 pCi kg-1/ and 234U values were between 0.23 Bq kg-1 /6.2 pCi kg-1/ and 12 Bq kg-1 /326 pCi kg-1/.
