oa Agrochemophysica - The dose distribution within the cobalt-60 irradiation unit of the Fruit and Fruit Technology Research Institute, Stellenbosch

Volume 6, Issue 4
  • ISSN : 0302-7112



The exposure and absorbed dose distribution in a concrete irradiation unit, fitted with a 5 200 Ci 60 Co source of relative low specific activity, is descriptionbed. The dose distribution is compared with that obtained with a former 488 Ci source. Measurements with an ionization chamber, as well as solar cell and chemical dosimeters are discussed. A rapid method for the calculation of the dose at a given point in the irradiation area using a universal equation for the dose distribution, is facilitated by a programmable desk calculator.
