ambient dose equivalent, CR-39, track density; neutron fluenceAbstract
Mediante detectores de trazas tipo CR-39 se determinó la dosis equivalente ambiental H*(10) por neutrones rápidos y térmicos en un acelerador Varian Clinac 2300 que opera en el rango de 6-18 MV. Mediciones preliminares fueron efectuadas ante una fuente moderada de neutrones 252Cf para obtener la respuesta del detector según el rango de energía. Se obtuvieron valores de tasa de densidad de trazas, flujo y dosis equivalente ambiental H*(10) por neutrones rápidos y térmicos en la mesa de tratamiento del recinto. Se determinó que la dosis equivalente ambiental H*(10) por unidad de dosis Gy en el isocentro (IC) es de 162 ± 11 μSv/Gy a una distancia de 13 cm del IC. Se presentan igualmente valores de flujo y tasa de densidad de trazas en el cabezal del acelerador.
