Research ArticleOpen accessPhrase in the titleRadiation Hazards Due to Radon Concentrations in Dwellings of Kufa Technical Institute, 'Iraq'Ali Abid Abojassim Al-Hamidawi, Afnan Ali HusainRadon concentrations were measured in Kufa dwellings of the technical institute, Al-Najaf- Iraq using LR-115 type II plastic track detectors. Additionally, annual effective dose and the excess lifetime cancer risk for the aforementioned dwellings were calculated. The results demonstrate that the radon concentration ranged from 37.4±6.4 Bq/m3 to 55.7±12.0 Bq/m3 with an average of 46.2±8.2 Bq/m3. The latter is found … …Physics International, Vol. 7, Issue 1 · 15 Apr 2016 · 8,143 accessesView PDFCite
Research ArticleOpen accessIn the abstractMEASUREMENT OF RADON EXHALATION RATE, RADIUM ACTIVITY AND ANNUAL EFFECTIVE DOSE FROM BRICKS AND CEMENT SAMPLES COLLECTED FROM DERA ISMAIL KHANNisar Ahmad, Mohamad Suhaimi Jaafar, Sohail Aziz Khan et al.Radon concentration, exhalation rate, radium activity and annual effective dose have been measured from baked and unbaked bricks and cement samples commonly used as construction material in the dwellings of Dera Ismail Khan City, Pakistan. CR-39 based NRPB radon dosimeters and RAD7 have been used as passive and active devises. The values of radon concentration for baked, unbaked bricks and … …American Journal of Applied Sciences, Vol. 11, Issue 2 · 21 Dec 2013 · 8,276 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Overview on Studying 222Rn Exhalation Rates using Passive Technique Solid-State Nuclear Track DetectorsMohamed Abd-ElzaherProblem statement: Uranium is a radiotoxic element found in trace quantities in alomost all natural accurring materials like soil, rock. Radon an inert radioactive gas whose predecessor in uranium, is emitted from soil beneath the house and from building materials. Accurate knowledge of exhalation rate plays an important role in characterization of the radon source strength in some building materials … …American Journal of Applied Sciences, Vol. 9, Issue 10 · 17 Aug 2012 · 8,510 accessesView PDFCite
