Estimation of the Radiation Field Homogeneity in Co-60 Blood Irradiator

Popis výsledku v původním jazyce

The aim of this work is to estimate the homogeneity of the radiation field in various configurations and relative activities of the "disposed" but still relatively highly active sources for their potential use in irradiation of blood (or blood derivatives). Small dose rate, which is already unusable/inappropriate for the teletherapy, may be still utilized by simultaneous use of multiple sources or reducing the distance to the irradiated object (blood unit). To estimate the homogeneity of the radiation field a modeling approach was chosen in which Monte Carlo code MCNP has been employed. (In-) homogeneity of the radiation field has been estimated on the basis of isodoses in the water phantom and various configurations and relative activities of the cobalt sources. The results are further discussed with regard to optimization (homogeneity of the sample irradiation, costs, radiation protection of service staff, availability of a sufficient number of resources, etc.).
