Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

The ability of clinoptilolite from the Chankanai deposit to take up 137 Cs from groundwater and liquid radioactive waste from the BN-350 reactor facility on the territory of TOO MAEK-Kazatomprom in Kazakhstan was studied. The results of semicommercial tests demonstrate the efficiency of using clinoptilolite as a reagent material of the geochemical barrier for preventing the radionuclide migration into groundwater in case of leakage of tanks for storage of liquid radioactive waste. A design of the geochemical barrier was suggested.
