RODRIGUEZ BALZA, J. J.  e  BARRUTIA BARRETO, I.. Dosis equivalente ambiental H*(10) por neutrones producidos en un Varian Clinac 2300 mediante detectores tipo CR-39. Rev. mex. fis. [online]. 2022, vol.68, n.2, e021101.  Epub 27-Mar-2023. ISSN 0035-001X.  https://doi.org/10.31349/revmexfis.68.021101.

Using CR-39 nuclear track detectors, ambient dose equivalent H*(10) by fast and thermal neutrons in a Varian Clinac 2300 medical accelerator operating in the range of 6-18 MV was determined. Preliminary measurements to obtain the detector response in a moderated 252Cf neutron source were made according to the neutron energy. Track density rate, fluence rate and ambient dose equivalent H*(10) values were obtained for fast and thermal neutrons in the couch. Ambient dose equivalent H*(10) per unit Gy dose at the isocenter was 162 ± 11 µSv/Gy at a distance of 13 cm from the isocenter. Track density rate and fluence rate in the linac head are also presented.

Palavras-chave : Ambient dose equivalent; CR-39; track density; neutron fluence.
