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

An algorithm and formulas to estimate non-regulatory stochastic risks (for biota and humans) have been derived. These were used to assess radiation risks for meadow plants within the Semipalatinsk Test Site (STS). It has been shown that on small plots with relatively high radiation levels (∼ 0.25 mGy/h) the radiation risks of death of radiosensitive plants (leguminous and coniferous shrubs) have a noticeable value (> 2%). In the other STS area, radiation is not a danger to the vegetation.
