چکیده

Standard neutron fields are invariably accompanied by a photon component due to the neutron-generating reactions and secondary neutron interactions in the surrounding environment. A set of energy-compensated Geiger-Müller (GM) tubes and electronic personal dosemeters (EPDs) have been used to measure the photon dose rates in a number of standard radionuclide and accelerator-based neutron fields. The GM tubes were first characterised in standard radioisotope and X-ray photon fields and then modelled using MCNP to determine their photon dose response as a function of energy. Values for the photon-to-neutron dose equivalent ratios are presented and compared with other published values.

Measuring the photon and thermal neutron dose values of contralateral breast surface undergone breast cancer radiation therapy

This research aimed to measure the received photon and thermal neutron doses to contralateral breast (CB) surface in breast cancer radiation therapy for different field sizes in presence of dynamic and physical wedges. The photon and thermal neutron doses were measured by thermo uminescent dosimeter (TLDs) chips for 11 × 13, 11 × 17 and 11 × 21 cm2 field sizes in presence of physical and dynamic ...

Validation of the Pinnacle3 photon convolution‐superposition algorithm applied to fast neutron beams

We evaluate a photon convolution-superposition algorithm used to model a fast neutron therapy beam in a commercial treatment planning system (TPS). The neutron beam modeled was the Clinical Neutron Therapy System (CNTS) fast neutron beam produced by 50 MeV protons on a Be target at our facility, and we implemented the Pinnacle3 dose calculation model for computing neutron doses. Measured neutro...

NATIONAL PHYSICAL LABORATORY Calibration and Monte Carlo Modelling of the NPL Long Counters

An extensive programme was successfully carried out during the 1995 to 1998 NMS programme to recalibrate and model by Monte Carlo simulations the characteristics of two NPL long counters that are routinely used to standardise neutron fluences [Ta98,Ta00] for neutron energies above 500 keV. The present work is a continuation of it in that the counters responses and effective centres have been me...

The Effect of Field Size and Distance from the Field Center on Neutron Contamination in Medical Linear Accelerator

Objective: Using Megavoltage photons generated by medical linear accelerator is a common modality for the treatment of malignant. The crucial problem for using photon beams >8MV is the photoneutron yields that increase the risk of secondary cancer that treated with high-energy photon beams. The contaminated neutrons produced in different components of the accelerator head and rely on many param...
