TITLE: Air Kerma Primary Standard: Experimental and Simulation Studies on Cs-137
نویسندگان
چکیده
The primary standard for air kerma for the gamma radiation of Cs-137, of the Metrological Laboratory of Ionising Radiation (LMRI), is an ionisation chamber of the type CC01. This instrument was, for the first time, used to characterize the radiation field, in terms of air kerma, produced by a Cs-137 source in an irradiator Shepherd model 81, used mainly for radiation protection calibration purposes. Monte Carlo simulation studies were also made, using MCNP5. These studies intend to characterize the radiation field by simulation of the irradiator and to obtain correction factors for this ionisation chamber.

Investigation of the air kerma response of spherical ionization chambers for unfolded pulse height distributions of (60)Co and (137)Cs using the EGS4 Monte Carlo code.
Data required for the determination of the absolute air kerma rate for (60)Co and (137)Cs gamma-rays using spherical cavity chambers were calculated using the EGS4 Monte Carlo system. Mass energy-absorption coefficient ratio and the stopping power ratio were calculated for a 10 cm(3) primary standard graphite-walled ionization chamber from the unfolded energy pulse height distributions of (60)C...

Monte Carlo photon-electron transport calculations have been done to derive new wall corrections for the six NBS-NIST standard graphite-wall, air-ionization cavity chambers that serve as the U.S. national primary standard for air kerma (and exposure) for gamma rays from (60)Co, (137)Cs, and (192)Ir sources. The data developed for and from these calculations have also been used to refine a numbe...

Brachytherapy describes a process where radioactive sources are inserted directly into the target area of a patient to treat disease. Before they can be used for treatment, brachytherapy sources must be calibrated such that medical physicists know their exact air kerma strength a quantity given by manufacturers as a standard. Each individual source must be measured before use. Therefore, medica...
متن کاملComparison of the air kerma standards for 137 Cs and 60 Co gamma - ray beams between the IAEA and the NIST
A comparison of the air kerma standards for Cs and Co gamma ray beams was performed between the NIST and the IAEA. Two reference class ionization chambers owned by the IAEA were used as part of this comparison and were calibrated at each facility. The calibration coefficients, NK, were determined for both chambers and in both gamma-ray beams. The measurements were performed at the IAEA and NIST...
متن کاملEstablishment of air kerma reference standard for low dose rate Cs‐137 brachytherapy sources
A guarded cylindrical graphite ionization chamber of nominal volume 1000 cm3 was designed and fabricated for use as a reference standard for low-dose rate 137Cs brachytherapy sources. The air kerma calibration coefficient (N(K)) of this ionization chamber was estimated analytically using Burlin's general cavity theory, as well as by the Monte Carlo simulation and validated experimentally using ...
