Abstract

The occupational and public potential radiological assessment and the health implications of medical facilities of southern Niger Delta, Nigeria on patients, health workers and the general public were conducted using a well calibrated Red-Alert 200 nuclear meter with Geiger-Muller tube. This study was conducted to established radiation safety level of the medical facilities and to ascertain health implication of patients, health workers and the general public. The mean radiological results of Private clinics, General Hospitals and Health Centres are 0.015 mR/hr, 0.012 mR/hr and 0.013 mR/hr respectively. The obtained mean result does not surpass the world recommended limit 0.013 mR/hr. The mean computed radiological risk values of absorbed dose rate (ADR), annual effective dose equivalent (AEDE) and Excess lifetime cancer risk (ELCR) are 116.0 nGy/hr, 0.572 mSv/yr and 0.199 respectively; the values are all within recommended limit. Also, the mean computed body organ (BDorgan) effective dose results and the contributed percentage of the three medical facilities studied are 0.3830 (15%), 0.3316 (13%), 0.3945 (15%), 0.4687 (18%), 0.3544 (14%), 0.2630 (10%) and 0.3888 (15%) mSv/yr for lungs, ovaries, bone marrow, testes, kidney, liver and whole body respectively. The obtained results of the medical facilities are all below recommended world limit of 1.0 mSv/yr. The measured, computed results of radiological risk and body organ (BDorgan) effective dose of the medical facilities studied does not pose significant radiological health risk on patients, health workers and the general public. However, precautions should be taken to avoid accumulation of radiations in the medical facilities.
