What is the concentration of reactor produced radioactivity in air at the specified distance, can you give a table?
Gaseous radioactive effluents are released through tall stacks of about 100 m on routine basis. Concentration distribution is a function of distance, wind speed and weather category. For an elevated release, the concentration will increase, reach a peak and then decrease along the downwind distance and the distance at which peak concentration occurs depends on the height of release and weather category. Ground level concentration for single plume of 1 Bq/s release at 100 m height for 1 m/s wind speed Concentration Bq/M3 for weather category.
