Abstract

Indoor radon exposure constitutes a significant public health concern , being the second leading cause of Lung cancer after smoking. Upon inhalation, radon dissolve in blood and is distributed to multiply body organs.This study measured indoor radon concentration in 50 rooms around hostels in LAUTECH Ogbomoso using calibrated RAD7 active electronic detector. Measured indoor radon concentration were subsequently integrated into a validated Physiologically base Pharmacokinetics (PBPK) model to simulate radon intake and distribution. Concentrations range from 2.44 - 183.44 Bq/m3 with mean of 76.46 Bq/m3. A cluster of low concentration (1-10 Ba/m3, 32%), moderate (30 -100 Ba/m3 28%) and high (100 -180 Bq/m3, 40 %). The mean is below the 100Bq/m3 reference level recommended by WHO. Bone marrow exhibited the highest radon retention (47.4%) and highest annual effective dose 0.1776 mSv/y and the heart recorded the lowest retention (2.3 %) and effective dose of 0.0007 mSv/y.  All organs effective dose were below the 1 mSv/y recommended by International commission on radiological Protection ICRP. The findings indicate that students in this environment are not at immediate radiological risk: however continuous monitoring , improved ventilation, adherence to the ALARA principle are strongly recommended
