O desenvolvimento e calibração de um sistema dosimétrico de rotina baseado no fotodiodo comercial e de baixo custo (SFH 206) é apresentado neste trabalho. A sonda dosimétrica foi projetada para operar sem tensão de polarização no modo de corrente direta. As radiações foram realizadas no irradiador Panorâmico de Cobalto-60 no intervalo de taxas de dose de 8,1 Gy/h a 125 Gy/h. As fotocorrentes geradas no diodo, para cada taxa de dose, foram registradas utilizando um eletrômetro digital e foram armazenadas durante todo o tempo de exposição.

O processamento por radiação está presente em diversos produtos tais como: alimentos, materiais médicos descartáveis, cabos elétricos, gemas, entre outros. O uso da radiação tem a finalidade de melhorar as propriedades dos produtos, esterilizá-los ou higienizá-los. Nos irradiadores industriais, as radiações eletromagnéticas (gama e raios-X) ou de elétrons, antes de interagirem com os produtos em beneficiamento, encontram uma camada de ar. Ao interagirem com esta camada, provocam efeitos radiolíticos nas moléculas presentes na atmosfera ambiente, sendo a principal interação a que ocorre com as

A dose rate measurement survey was performed at various locations inside the radiation chamber of the Cobalt-60 gamma irradiation facility located in Room 130, Building 20 at the University of Arizona. TLDs were used for the dose rate measurements. It was observed that the dose rates decrease rapidly with increasing distance from the source. Also, dose rates decreased with increased distance away from the centerline of the radiation chamber which is indicative of the position of the effective center of the source.

According with the requirements of HAF-102[1], the purpose of radiation protection optimization is to achieve occupational exposures as low as reasonably achievable (ALARA). More than 80% of the collective exposure doses are received during the outage for PWRs. Activated corrosion products, especially Co-60, deposited on the surface of reactor coolant system are the main causes of these doses. Co-60 is the principle contributor to out-of-core radiation fields in PWRs, which is a high energy gamma emitter with a 5.3 year half-life period.
