The accumulation of cesium-137 by the cap and stalk of fruiting bodies of Leccinum aurantiacum (Bull.) Gray from the podzolic soil of an aspen forest 30-35 years old was compared with spruce undergrowth, which resumes after felling and damage to the litter. The average specific activity of caesium-137 for dry caps is 1589±85 Bq/kg and for stems 879±72 Bq/kg. It has been established that the specific activity of cesium-137 does not exceed the allowable values. The coefficients of accumulation of cesium-137 by parts of fruiting bodies from the soil vary in the following range: for caps from 5.4 to 6.8, and for legs from 1.2 to 2.8. The maximum specific activity of caesium-137 was found in the forest litter 461±54 Bq/kg. With increasing depth, it naturally decreases. |
