Characterization of a new radiochromic film (LD-V1) using mammographic beam qualities
Purpose: Radiochromic film (RCF) is a detector that can obtain a two-dimensional dose distribution with high resolution; it is widely used in medical and industrial fields. Several types of RCFs exist based on their application.

MTS-6 detectors calibration by using 239Pu-Be neutron source
Background: Thermoluminescent detectors, type MTS-6, containing isotope 6Li (lithium) are sensitive in the range of thermal neutron energy; the 239Pu-Be (plutonium-and-beryllium) source emits neutrons in the energy range from 1 to 11 MeV. These seemingly

Abstract Background Clinical dosimetry for kV X‐ray radiotherapy beams requires calibrated ionization chambers. When the clinical field size differs from the field size used for chamber calibration, in‐air measurements result in a different magnitude of scatter from the detector stem or body housing affecting the sensitive volume.

Abstract Background In boron neutron capture therapy (BNCT), Monte Carlo (MC) dose calculations are commonly employed because of the complicated neutron reactions. However, MC dose calculations are generally time‐consuming. Recently, deep learning (DL)‐based dose prediction/calculation has attracted increasing attention; however, the applications of DL

The Ratio between Absorbed Dose, Kerma and Ionization Kerma for Small-size Fields
Purpose: Research of the relationships between spatial distributions in water of the main dosimetric values, namely the absorbed dose, kerma and ionization kerma, for small-size fields with a circular cross section created by divergent beams of bremsstrahlung spectrum with a maximum energy of 6 MeV. Material and methods: Using the Monte-Carlo ...

Comparison of the NIST and ENEA air kerma standards
A comparison was made between the National Institute of Standards and Technology (NIST) and Ente per le Nuove Tecnologie l'Energia e l'Ambiente (ENEA) air kerma standards for medium energy x rays and 60Co gamma rays. The comparison took place at ENEA in June 1994. Two different transfer chambers from NIST were used for the comparison.
