“…This detector had an attached photomultiplier tube (XP4512B, Photonics, Pittsfield, MA, USA) and 12 bit, 250 MHz waveform digitizer (V1720, CAEN Technologies Inc., Staten Island, NY, USA). Commercially available mathematics software package (MATLAB, Matick, MA, USA) was employed to implement an optimized PSD method [10,11], with a minimum threshold set to 80 keVee. The Compton edge in the PHD for a 137 Cs check source, at 447 keV, determined the detector light-output-to-energy conversion factor.…”

“…Calculation of the simulated PHDs required both MCNP-PoliMi as well as a custom Fortran-based post-processor [11] that calculated detector response, compiling the interaction data into pulse height and time-of-flight distributions. To accomplish this, the post-processor calculated light output (MeVee) in the detector such that the light produced by photon interactions was equal to the energy deposition (MeV).…”

“…in which light output in detector B, L (MeVee) was a quadratic function of neutron energy deposition, E (MeV) [11]. The resulting calculated neutron PHDs were compared with the measured neutron PHD isolated using the aforementioned PSD techniques.…”

The Linear particle accelerator (LINAC) is a tool for radiation therapy that can emit photons and electrons. Radiation of X-ray photons and LINAC electrons is obtained from the interaction of electrons fired into the target plate (tungsten). This radiation can not only affect the target organ but can also affect unwanted organs around the exposure area. Radiation irradiation effects on the organs in the exposure area can be known through simulation of LINAC and phantom radiation processes. Simulation and calculation using Monte Carlo method. This program is operated by MCNPX software. Phantom geometry uses the phantom ORNL MIRD, whereas linac geometry consists of linac blankets, tungsten plates and collimators. Radiation from linac is directed to the left lung as a target and from the simulation results of traces of radical particles shows that radiation emission from linac there are some scattering, but scattering this does not have a significant impact because the amount is not too large. Radiation effect on the organs is indicated by the effective dose quantities in which the left lung has a greater effective dose than the surrounding organs. While the right lung gets a large enough effect from other organs around the target organ. This is because the organ is located close to the target organ and has a smaller type of meeting of the other organs. Not so with the ribs, although it is the first organ exposed to radiation. Radiation that concerns the ribs has no significant effect. This is because of the enormous type of meeting. The effects of radiation on organs are not only influenced by the size of the meeting of organ types but also influenced by the weight factor.
