Radioactive contamination of wood and its products

摘要

This paper presents research on radioactive contamination of the three most common kinds of wood in Croatia-beech, oak and fir as well as acorn. Gamma-spectrometric measurements carried out on the samples of bark and wood of beech, oak, fir and acorn have shown radioactivity contents ranging from 1.6 ± 0.1 to 37.3 ± 0.5 Bq/kg from deposited ~137Cs, whose concentrations in the soil of Croatia have increased after the Chernobyl accident.
