The radiation dose received by human beings from the radiation emitted by these naturally occurring radionuclides is approximately 87%. Exposure to radiation poses radiological health hazards. To assess the human health hazards from radiation, the concentration of these naturally occurring radionuclides are measured in soil (used for cultivation), building materials (soil, bricks, sand, marble, etc.), water and dietary items, worldwide. The available literature revealed that numerous studies related to the subject have been carried out in Pakistan. Most of these studies measured the radioactivity concentrations of primordial [uranium (<jats:sup>238<\/jats:sup>U), thorium (<jats:sup>232<\/jats:sup>Th), radium (<jats:sup>226<\/jats:sup>Ra) and potassium (<jats:sup>40<\/jats:sup>K)] and anthropogenic [cesium (<jats:sup>137<\/jats:sup>Cs)] radionuclide in soil samples (used for cultivation), fertilizers, building materials (i.e. bricks, rocks, sand, soil, marble, etc.), as well as water and dietary items, using a sodium iodide detector or high purity germanium. An effort was made in 2008 to compile these studies as a review article. However, since then, considerable studies have been undertaken and reported in the literature. Therefore, the main objective of the present article is to provide a countrywide baseline data on radionuclide levels, by overviewing and compiling the relevant studies carried out in Pakistan.<\/jats:p>","DOI":"10.1515\/reveh-2018-0058","type":"journal-article","created":{"date-parts":[[2019,2,12]],"date-time":"2019-02-12T09:12:27Z","timestamp":1549962747000},"page":"141-152","source":"Crossref","is-referenced-by-count":8,"title":["An overview of radioactivity measurement studies in Pakistan"],"prefix":"10.1515","volume":"34","author":[{"given":"Wazir","family":"Muhammad","sequence":"first","affiliation":[{"name":"Therapeutic Radiology, Yale-School of Medicine, Yale University , New Haven, CT 06520-8040 , USA , Phone: +1 (203) 785-2368, Fax: +1 (203) 785-4765"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"family":"Matiullah","sequence":"additional","affiliation":[{"name":"Directorate of Systems and Services , Pakistan Institute of Nuclear Science and Technology (PINSTECH) , Islamabad , Pakistan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Asad","family":"Ullah","sequence":"additional","affiliation":[{"name":"Health Physics Division (HPD) , Pakistan Institute of Nuclear Science and Technology (PINSTECH) , Islamabad , Pakistan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sajjad","family":"Tahir","sequence":"additional","affiliation":[{"name":"Department of Nuclear Engineering (DNE) , Pakistan Institute of Engineering and Applied Sciences (PIEAS) , Islamabad , Pakistan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fawad","family":"Ullah","sequence":"additional","affiliation":[{"name":"Department of Physics , Kohat University of Science and Technology , Kohat , Pakistan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Matiullah","family":"Khan","sequence":"additional","affiliation":[{"name":"Department of Physics , Kohat University of Science and Technology , Kohat , Pakistan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"374","published-online":{"date-parts":[[2019,2,12]]},"reference":[{"key":"2021021407413679544_j_reveh-2018-0058_ref_001_w2aab3b7c12b1b6b1ab2b1b1Aa","doi-asserted-by":"crossref","unstructured":"Alam M, Chowdhury MI, Kamal M, Ghose S, Islam MN, Mustafa MN, et al.
