The Journal of Environmental Radioactivity provides a coherent international forum for publication of original research or review papers on any aspect of the occurrence of radioactivity in natural systems. Relevant subject areas range from applications of environmental radionuclides as mechanistic or timescale tracers of natural processes to assessments of the radioecological or radiological effects of ambient radioactivity.

Information about source points of anthropogenic radioactivity. Public safety consequences and radioecological impact of nuclear accidents and nuclear industries.

Laboratory for Radioecology, located at Nakaminato, Ibaraki Prefecture, consists of two Divisions (Radioecology and Marine Radioecology) and an Administration Section. Since the establishment of NIRS, the environmental behavior of radionuclides has been one of the main subjects of study. A Division(Radioactive Contamination) at Chiba campus had responsibility for the environmental radioactivity study.

The Radiation Physics and Radiocarbon Research Laboratory specialises in the measurement of minute traces of artificial and natural radionuclides in the environment. The laboratory is equipped with state-of-the-art facilities for high resolution alpha spectrometry, low-level beta spectrometry, and high resolution gamma and x-ray spectrometry. Advanced radiochemical separation techniques for nuclides such as plutonium, uranium, thorium, americium, technetium, radiostrontium and radiocaesium have been developed. We also apply radiometric dating techniques for reconstructing environmental histories.

The Radiocarbon Section of I.Javakhishvili Tbilisi State University was established in 1958-1963 at Physics Faculty under the supervision of prof. M.Mirianashvili, prof. V.Kokochashvili and prof. A.Burchuladze. Since that time, the Laboratory staff has made considerable contribution in investigations of the problems of archeology, paleobotany, paleogeography, and geology in Georgia.

EPA's resource for information on Biological Criteria, Assessment, and Indicators. Chapter 2 of "Biological Criteria: National Program Guidance for Surface Waters". This chapter covers sections of the Clean Water Act that relate to biological assessments and biocriteria. For instance, Section 303(c)(2)(B) requires States to adopt criteria bases on bioassessments and Section 304(a)(8) directs EPA to develop and publish guidance.
