On line high dose static position monitoring by ionization chamber detector for industrial gamma irradiators

A 1 cm3 cylindrical ionization chamber was developed to measure high doses on line during the sample irradiation in static position, in a 60Co industrial plant. The developed ionization chamber showed to be suitable for use as a dosimeter on line. A good linearity of the detector was found between the dose and the accumulated charge, independently of the different dose rates caused by absorbing materials.
