APPLICATION OF NITROGEN FLUORESCENCE FOR THE DOSIMETRY OF ELECTRON-BEAM

The fluorescence of air which was excited by fast electrons of 0.5 to 1.5 MeV has recently been suggested to measure the spatial distributio n of dose rate in gas phase at room temperature and under atmospheric pressure. The radiation-induced light intensity in the spectral range from 290 to 650 nm apear to be the linear function of the EB dose rate . Accurately determined energy of electrons of small power VdG acceler ator was applied to calibration in the method. The first results of th e method seem to be promising, especially for gas phase EB irradiation s, such as radiation induced desulfurization and denitrification of in dustrial flue gases
