Incidencia oblicua: radiación dispersa

Some effects of the dispersed radiation were studied when a Co-60 beam impacts obliquely on a target (fantoma), of similar composition to biológical tissue (water). The process of was simulated by means of thc method Monte Carlo (MC) relating it to variations of the angle of incidence of the radiati...

The process of was simulated by means of thc method Monte Carlo (MC) relating it to variations of the angle of incidence of the radiation beam, regarding the interface air-fantoma.To analyze the phenomenon of oblique incidence it was considered fields of 4x4 cm and carrying out the separation of the primary and secondary contributions.

Se estudiaron algunos efectos de la radiación dispersa cuando un haz de Co-60 incide oblicuamente sobre un blanco (fantoma), de composición similar a tejido biológico (agua). El proceso de simuló mediante el método Monte Cario (MC) relacionándolo a variaciones del ángulo de incidencia del haz de radiaciones, respecto de la interfase aire-fantoma.Para analizar el fenómeno de incidencia oblicua se consideró campos de 4x4 cm y realizando la separación de las contribuciones primaria y secundaria. En el se halló que la dosis en el eje central no se ve alterada al variar el ángulo de incidencia, aunque si lo hace la curva de rendimiento en profundidad (H), fundamentalmente como consecuencia del desplazamiento del pico de máxima ionización.  Facultad de Ciencias Exactas y Naturales y Agrimensura 2000-12-15 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion application/pdf https://revistas.unne.edu.ar/index.php/fce/article/view/7881 10.30972/fac.1617881 FACENA; Vol. 16 (2000); 3-14 1851-507X 0325-4216 spa https://revistas.unne.edu.ar/index.php/fce/article/view/7881/7345
