This paper does not necessarily reflect the views of the International Commission on Radiological Protection. The protection quantity 'effective dose' was developed by the International Commission on Radiological Protection (ICRP) for use in the radiological protection of workers and the public. In this context, it is used as a risk-adjusted dosimetric quantity to optimise protection, comparing...

A procedure for the calibration of instruments for the detection of 222Rn in air is described. The method is based on the alpha-spectrometric determination of the concentration in air of 218Po in the calibration chamber. The calibration chamber is described, together with the method of maintaining a high aerosol concentration. The 218Po concentration at steady state in the chamber is found to b...

Predominantly with cells in vitro but also with whole animals in vivo it has been shown that small radiation doses like other stress factors can render cells or organisms to a stage of higher radioresistance. This has been demonstrated with chromosomal aberrations, gene mutation, cell transformation and survival. However, it is necessary to keep the appropriate conditions in a very stringent wa...

Pursuant to Article 1 of the Convention signed in Paris on 14th December 1960, and which came into force on 30th September 1961, the Organisation for Economic Cooperation and Development (OECD) shall promote policies designed: − to achieve the highest sustainable economic growth and employment and a rising standard of living in Member countries, while maintaining financial stability, and thus t...

During the past years, special emphasis was put on medical preparedness in the event of radiological or nuclear emergencies. Novin Medical Radiation Institute (NMRI) encouraged and supported the national authorities to enhance their cooperation in improving medical response to radiation accident. NMRI in cooperation with International Atomic Energy Agency (IAEA) and Atomic Energy Organization o...

All soils and rocks contain naturally occurring radioactive material (NORM). Many ores and raw materials contain relatively high levels of natural radionuclides, and processing such materials can further increase the concentrations of natural radionuclides, sometimes referred to as 'technologically enhanced naturally occurring radioactive material' (TENORM). Examples of NORM minerals include ur...

ENRESA is the national company in charge of radioactive waste management in Spain. The company was set up in 1984, and one of its missions is the dismantling of nuclear facilities. ENRESA has carried out the dismantling of the Vandellós 1 nuclear power plant, several research installations and a pool type experimental reactor and is currently initiating the dismantling of the José Cabrera nucle...

The OECD is a unique forum where the governments of 30 democracies work together to address the economic, social and environmental challenges of globalisation. The OECD is also at the forefront of efforts to understand and to help governments respond to new developments and concerns, such as corporate governance, the information economy and the challenges of an ageing population. The Organisati...
