A new radioactive substances regulatory regime came into effect across the UK on 1 October 2011, accompanied by Government and regulator's guidance. The legislation sets new activity thresholds for what is within its scope and for what is exempt from the permitting requirements. These thresholds are, for the first time, clearly based on the levels in the Basic Safety Standards Directive; distinguish between NORM industrial activities and practices; and are derived from different dose constraints. There are new exemption provisions for NORM, aqueous liquids and gaseous wastes.

“…Radioactive waste is generated in practices that use radioactive materials during relevant operational processes. These practices include all uses of radionuclides in industry, medicine, and research [1,2]. After generation, and before transportation to final disposal, untreated radioactive waste must be treated and conditioned.…”

Radon exposure at a radioactive waste storage facility

et al. 2014

The Waste Management Department of Nuclear and Energy Research Institute (IPEN) is responsible for the safety management of the waste generated at all internal research centers and that of other waste producers such as industry, medical facilities, and universities in Brazil. These waste materials, after treatment, are placed in an interim storage facility. Among them are (226)Ra needles used in radiotherapy, siliceous cake arising from conversion processes, and several other classes of waste from the nuclear fuel cycle, which contain Ra-226 producing (222)Rn gas daughter.In order to estimate the effective dose for workers due to radon inhalation, the radon concentration at the storage facility has been assessed within this study. Radon measurements have been carried out through the passive method with solid-state nuclear track detectors (CR-39) over a period of nine months, changing detectors every month in order to determine the long-term average levels of indoor radon concentrations. The radon concentration results, covering the period from June 2012 to March 2013, varied from 0.55 ± 0.05 to 5.19 ± 0.45 kBq m(-3). The effective dose due to (222)Rn inhalation was further assessed following ICRP Publication 65.

A brief description is provided of the basic concepts related to 'internal dose' and how it differs from doses that result from radioactive materials and direct radiation outside of the body. The principles of radiation dose reconstruction, as applied to both internal and external doses, are discussed on the basis of a recent publication prepared by the US National Council on Radiation Protection and Measurements. Finally, ideas are introduced related to residual radioactive contamination in the environment that has resulted from the releases from damaged reactors and also to the management of wastes that may be generated in both regional cleanup and decommissioning of the Fukushima nuclear power plant.
