Lichens and mosses as polonium and uranium biomonitors on Sobieszewo Island

摘要

In the study the activities of polonium ²¹⁰Po and uranium ²³⁴U, ²³⁸U radionuclides in moss and lichen samples were determined using the alpha spectrometry. Different lichens and mosses were collected around the Sobieszewo Island (northern Poland) and investigated for potential use as biomonitors for ²¹⁰Po and ²³⁸U deposition. Mosses and lichens have a high efficiency in capturing ²¹⁰Po and ²³⁸U from atmospheric fallout. The obtained results showed that ²¹⁰Po, ²³⁸U concentrations are changing in analyzed thallophytes samples depending on the type of thallus.
