An overview on measurements of natural radioactivity in Malaysia. Journal of Radiation Research and AppliedSciences, 8 (1). pp. 136-141. ISSN 1687-8507 (2015)
Abstract
Humans are always exposed during their lives to ionizing radiation arising outside and within the earth. The exposure to these radiation occurs from natural sources such as radioactive elements in rocks and soil, internal exposure form radioactive elements through water, food and air and cosmic rays entering from outer space to earth's atmosphere. About 87% of the radiation dose received by human beings is due to natural radiation, it is essential to assess the radiation doses in order to control possible healtheffects from such natural sources. In this regard, a number of articles have been appearedfor Malaysia in international research journals, which have been reviewed and complied inthis article. Most of these articles are about the measurement of activity concentrations ofprimordial (238U,232Th,226Ra and40K) and anthropogenic (137Cs) radionuclide's and gammadose rate in environmental samples using HPGe and NaI (Tl) survey meter.
