Abstract:
This paper discusses the links between radioecology and radiation protection. The traditional radiation protection framework of the International Commission Radiological Protection (ICRP), adopted by the legislation of most countries, is shifting from the paradigm that "if man is adequately protected from ionizing radiation, then other living things are also likely to be sufficiently protected" towards more efficient protection of non-human biota. However, the estimation of radiation doses, especially low ones, to non-human organisms is very complex issue since they have been studied to a far lesser extent compared to human doses. The first step in dose calculations (i.e. risk assessment) is the measurement of real field data for various radionuclides in various compartments of the biosphere as well as dose rate measurements. Once we obtain relevant data, it is reasonable to argue that biota is adequately protected if the dose rates to the maximally exposed individual from this population are below a certain (safe) limit. The problem arises when one attempts to identify such an individual within a contaminated environment described by measured radioecological parameters. Computer simulation techniques, like Monte Carlo methods are used to generate a "population" of doses with known distributional qualities. Then, using statistical methods, a part of this population is mathematically "sampled" to compare the ability of the various statistics at estimating the representative sample of maximally exposed individuals. This exposure, depending on environmental conditions is subject to radioecological investigations. Radioecological investigations regarding fission products in Croatia are implemented as part of an extended and still ongoing radioactive contamination monitoring programme of the human environment that has been fully harmonized with European legislation, i.e. the European Commission’s recommendation of June 2000 on the application of Article 36 of the Euratom Treaty.
