摘要：
The concentration of Ra isotopes in environmental water can be determined from the amount of Ra isotopes recovered in two successive batch operations using a cation exchange resin. The present analytical method is applicable to 10 liter of sample water having a Ra concentration larger than 10 mBq/l and is also applicable to ordinary underground water of less than 1 mBq/l by use of 50 liter of sample water. In the case where Ra concentration is extremely low, Mn-impregnated acrylic fiber can be used with a larger volume of water sample as an absorbent by soaking it in the water.
