Environmental Badges
Analysis
For the analysis Phase of this project, the rate of exposure is required. For this to be determined some assumptions were made; the environmental badges received 10 mrem/quarter of exposure, the synchrotron equally exposes the entire facility; the Radiation follows the Inverse Square law for the relation of exposure to 2 points away from a source, and all other factors of exposure attenuation were ignored. These assumptions simplified the calculations to only be dependent on the distance to the exterior of the facility. Using the Proximity tool; the distance between the badges and the exterior of the facility was determined. The average distance was 125.6 meters. Utilizing the average distance and exposure of the environmental badges …show more content…
A buffer based on limiting facility exposure to the occupational exposure limit of 5 mrem annually. The buffers from this limitation resulted in a 2.25m public exposure limit and 9m background buffer. This buffer resulted in only 458 people being in the same block as elevated radiation exposure. The buffer region is viewable in the map title Exposure due to CAMD: Worker limited. The last buffer calculated was for a hypothetical Emergency Response situation. For this the facility exposure was set to 10 R/hr, the EPA defined a limit for ER exposure. For this buffer, ranges were calculated for 100mR/hr, 5mR/hr, 2mR/Hr and .003 mR/hr. These exposures are the limits for high radiation area, radiation area, public exclusion and twice background respectively. These ranges would require proper indication in the event of an Emergency Response. The ranges for this multi-ring buffer were 10m 45m 71m and 1826m. IN this event zero members of the public would be beyond the public exclusion zone, 458 would be inside the same black as the event, and 10204 people would be exposed to elevated radiation levels.
