摘要：

In this paper the authors propose a search for **9**9Tc in flocs from water treatment plants. It is shown that preconcentration of **9**9Tc from environmental waters is a very advantageous method because of the high volumes involved. A radiochemical method is adapted in these kinds of samples, and **9**9Tc is identified in them by a previously published method. A typical value found is 0. 56 plus or minus 0. 26 mBq/g, where 1 g dry floc should be related to many liters of water.
