    Indium is activated, principally by epithermal neutrons, to give 114Inm with a half-life of about 50 d. Indium foils exposed in the UK criticality dosemeter, at an International Intercomparison Experiment at the SILENE ...
  • Dumitru C.; Lungu C.; Iosif S. (Oxford University Press, 1992-07-01)
    Post Chernobyl 134Cs and 137Cs body contamination was measured in 2883 adults (1656 males and 1227 females) in the Bucharest area from July 1986 to December 1989 using a whole-body counter with single detector tilting chair ...
  • Zvonova I.A.; Jesko T.V.; Balonov M.I.; Danilova I.O.; Wallström E.; Alpsten M.; Thornberg C.; Mattsson S. (Oxford University Press, 1995-12-01)
    Six western districts of the Bryansk region, Russia, were heavily contaminated with radioactive fallout after the Chernobyl NPP accident. Annually, between 1991 and 1994, inhabitants of four settlements were studied. ...
  • Tarroni G.; Melandri C.; Battisti P.; Castellani C.M.; Formignani M.; Rampa E. (Oxford University Press, 1990-09-01)
    A synthesis of the data concerning the distribution and behaviour over time until September 1989 of 134Cs and 137Cs human contamination deriving from the accident to Unit 4 of the Chernobyl Nuclear Power Station on 26 April ...
  • Johansson L.; Ågren G. (Oxford University Press, 1994-09-01)
    Whole-body content of 137Cs has been measured in both 1991 and 1992 in the population of northern Sweden, with a special interest taken in the Saami population. Measurements were performed in three areas with different ...
  • Sims C.S. (Oxford University Press, 1986-05-01)
    The Health Physics Research Reactor (HPRR) has recently undergone modifications associated with its positioning mechanism. While the core and the control rods were unchanged, structural materials near the core were ...
  • Hedvall R.; Erlandsson B. (Oxford University Press, 1988-08-01)
    210Pb is probably one of the major contributors to the radiation dose received by humans from the fumes emitted from the stacks of power plants using fossil fuels or biofuels. As a first step in the estimation of the total ...
  • Köster H.W.; Marwitz P.A.; Berger G.W.; Van Weers A.W.; Hagel P.; Nieuwenhuize J. (Oxford University Press, 1992-12-01)
    Surveys of Dutch waters show that the Oosterschelde estuary and regular fresh waters have the lowest levels of 210Po, 210Pb and 226Ra. Elsewhere effluents from phosphates and iron ore processing industries cause nearby ...
  • Samuelsson C.; Johansson L.; Wolff M. (Oxford University Press, 1992-12-01)
    Long-lived radon decay products implanted by alpha recoils into indoor surfaces can be used to reveal past radon concentration levels. Owing to its availability, physical and electrical properties, etc. sheets of glass are ...
  • Azerado A.M.G.F.; Lipsztein J.L. (Oxford University Press, 1991-04-01)
    210Po concentrations in urine samples from individuals exposed in different areas of a uranium milling and mining complex in Brazil were measured, in search of possible indications of internal contamination by Rn and ...
  • Carvalho F.P. (Oxford University Press, 1988-08-01)
    Marine biota is able to concentrate 210Po to high levels, as 103-105 relative to sea water concentration. 210Po concentrations in mixed zooplankton reaches 34-51 Bq.kg-1 (fresh wt), special groups such as copepods reaching ...
  • Bigu J. (Oxford University Press, 1991-01-01)
    Concurrent measurements of 220Rn and 220Rn progeny were conducted in an underground uranium mine. The 220Rn measurements represent the first accurate source of data for Canadian mines. Furthermore, a study of the ratio ...
  • Harley N.H.; Robbins E.S. (Oxford University Press, 1992-12-01)
    The alpha dose to cells in tissues or organs other than the lung has been calculated using the solubility coefficients for 222Rn measured in human tissue. The annual alpha dose equivalent from 222Rn and decay products in ...
  • Harley N.H.; Meyers O.A.; Robbins (INVITED) E.S. (Oxford University Press, 1992-12-01)
    The alpha dose to cells in bronchial airways in the beagle dog during historical exposures to 222Rn decay products is calculated using updated information on airway morphometry, cell nucleus depth, mucus thickness, physical ...
  • Labed V.; Witschger O.; Robe M.C.; Sanchez B. (Oxford University Press, 1994-12-01)
    Radon emission flux at the ground-atmosphere interface is one of the measurements commonly made for environmental purposes and on prospective mining sites. There are a number of ways of making such measurements. Generally ...
  • Pereira E.B.; Setzer A.W.; Cavalcanti I.F.A. (Oxford University Press, 1988-08-01)
    222Rn was continuously measured at the Brazilian Antarctic Station (62 oS, 58 oW) during the year of 1986. Baseline radon concentration averaged 0.02 Bq.m-3 with surges peaking at 0.4 Bq.m-3. The data exhibited a characteristic ...
  • Godoy J.M.; Gouvea V.A.; Melo D.R.; Azerado A.M.G. (Oxford University Press, 1992-12-01)
    Over 30 tobacco leaf samples, obtained from major Brazilian cigarette producers or tobacco exporters, were analysed in order to investigate the radioactive equilibrium between 226Ra, 210Pb and 210Po. The results have shown ...
  • Pires do Rio M.A.; Godoy J.M.; Amaral E.C.S. (Oxford University Press, 1988-08-01)
    The Brazilian production of bottled mineral water is about 560 million litres per year. The states of Sao Paulo, Rio de Janeiro, Minas Gerais and Pernambuco are responsible for more than 65% of the total production. Over ...
  • Soto J.; Quindos L.S.; Diaz-Caneja N.; Gutierrez I.; Fernández P.L. (Oxford University Press, 1988-08-01)
    A preliminary study is presented, preliminary to a full-scale national survey on 226Ra and 222Rn levels in surface and underground waters in two regions of Spain of very different geological composition, which were selected ...
  • Carreiro M.C.V.; Sequeira M.M.A. (Oxford University Press, 1988-08-01)
    Uranium, thorium, and their decay products, being primordial radionuclides, are of interest in the nuclear fuel cycle. They have therefore been systematically considered in the radiological survey of the Portuguese rivers ...
