Radiation Risk Assessment on Public in Motijheel Thana, Dhaka, Bangladesh

Objective: The pollution free environment is required for healthy life. real-time radiation monitoring very important hazard detection in the environment. excess life-time cancer risk (ELCR) on public to assess based data area. Methods: was performed using portable digital device. This device meets all European CE standards as well American “FCC 15 standard”. placed at 1 meter above ground tripod and collection time each point (MP) hour. 27 MPs were chosen of various outdoor Motijheel Thana, Dhaka from May-August 2018.Results: dose rates Thana due natural radionuclides ranged 0.095 ± 0.041 µSv.h-1 0.185 0.042 with an average 0.147 0.047 µSv.h-1. annual effective environmental found be 0.166 0.066 mSv 0.324 0.061 0.257 0.039 mSv. Excess Life-time Cancer Risk are also estimated that 0.662 ×10-3 1.289 value 1.025 ×10-3, which higher than world 0.29×10-3. Conclusion: type study arising natu-ral man-made sources generation baseline database. From this study, it observed there no pose any area sources.
