Thermoluminescence dosimetry of mixed neutron – gamma fields

Dosimetry in Mixed Neutron-Gamma Fields

The gamma field accompanying neutrons may, in certain circumstances, play an important role in the analysis of neutron dosimetry and even in the interpretation of radiation induced steel embrittlement. At the figh Flux Isotope Reactor pressure vessel the gamma-induced reactions dominate the responses of ' W p and 238u dosimeters, and9Be helium accumulation fluence monitors. The gamma induced at...

Investigation of neutron flux by thermoluminescence dosimeters in the neutron-gamma mixed field

Introduction: Neutrons have many applications in various fields, such as medicine. The important application of neutron in medical science is in Boron Neutron Capture Therapy (BNCT). Because of this, determination of neutron dose and flux is critical for the health maintaining of workers and patients exposed to this beam. The neutron radioisotope sources produce gamma rays in ...

Design and manufacture of composite flexible shield for neutron-gamma mixed fields

In this study, a flexible composite shield with a combination of polyethylene, tungsten and boron carbide has been designed and constructed for neutron-gamma mixed fields. For this purpose, theoretical studies were conducted using the multi-purpose MCNPX Code. According to the results of simulation studies, a multi-purpose composite was constructed using a combination of a solid phase of boron ...

Thermoluminescence Study of 210C Glow Peak in Synthetic Quartz and their Application in High Gamma Dosimetry

The thermoluminescence (TL) properties of laboratory grown quartz have been studied for its possible high gamma dosimetric applications. The variation of 210 o C glow peak is observed in different annealed samples followed by gamma irradiation near room temperature. The peak was found very sensitive to the pre-thermal treatments. The radiation induced effects in quartz have been studied in deta...
