Hey ,

My classmates and I were asked to give a presntatoin about "food irradiation" and I'm the one who 's responsible about shielding calculations. I want to show that 6 m (19.69 ft) of water is enough to shield gamma source so that the exposure dose for workers doesn't exceed the maximum permissible dose(MPD) . For solving this I need to know :

1-The average total activity of gamma source array in curie.
2- The diminsion of the of gamma source array.

Hopefully someone can help me to get these parameters.

It depends on the type of irradiation machine. Some use Co-60, some use Cs-137, and others use electron beams. Not my specialty, but I imagine the activities of a Co-60 machine varies from machine to machine depending on what is being irradiated.

Food irradiation


If you can get your hands on a copy of John Lamarsh's book Introduction to Nuclear Engineering, you'll find all the basic information and formulas you need in a very easy format.
