Assessment of Indoor Ionizing Radiation Profile in Radiology Department FMC Asaba Delta State, Nigeria
Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2017, Vol 16, Issue 1
Abstract
A “Radiation Alert Inspector” survey meter was the instrument of choice used in measuring and obtaining the indoor ionizing radiation profile placed at 22 selected presumable hotspots of increase radiation (coded A1-A22) as identified by a global positioning system within the Radiology department of Federal Medical Centre (FMC) Asaba. Values obtained from the measurements were converted from micro Sievert per hour (μSv/hr) to mili Sievert per year (mSv/yr). The calculated mean indoor post exposure dose value was in the range of 0.09 – 0.20 μSv/hr (0.60-2.01 mSv/yr). The highest point with increased radiation dose was found to be in the diagnostic x-ray room (2.01±4.11 mSv/yr), while the lowest point was detected at the intern’s common room with a value of 0.60±0.3 mSv/yr. The overall mean of the Mean Indoor Post Exposure (mMIPE) was arrived at 0.88±0.28mSv/yr. Base on the aforementioned findings, it was deduced that radiation level were kept within permissible radiation limit as stipulated by the ICRP and UNSCEAR of 1mSv/yr and thus, FMC Asaba can be said to be Radiologically safe.
