Dosimetry of electron and gamma radiation with DL-alanine

This paper reports the application of powder DL-alanine/ESR dosemeter for measurement of the absorbed dose of Cobalt 60 gamma rays and electron beams. The sample preparation details are described, as well as the analysis of the ESR signal to dose, the energy response, the influence of dose rate and effect of the ambient conditions on the fading of the ESR signal. The irradiations were performed using a panoramic Cobalt 60 gamma ray source and electron emitted from an accelerator for industrial purposes. The obtained results give useful information on the care necessary to obtain the needed overall accuracy in the determination of absorbed doses
