Shielding of Radiation Fields Generated by Cf-252 in a Concrete Maze, Part 1- Experiment
نویسندگان
چکیده
A concrete room with a single-legged maze was constructed in order to simulate a medical accelerator room. Gamma and neutron measurements were performed along the maze with a) a 252 Cf source and b) a tungstenmoderated Cf source placed inside the room. The measurements were repeated after placing an inner borated polyethylene door of varying thickness (2.54 -10.16 cm) at 2 different locations. Measurements were also performed after lining the inside of the maze with different neutron moderating materials .The following results are reported: 1) the variation and contributions of individual components of the radiation fields as a function of distance along the maze 2) the attenuation of neutron dose equivalent and reduction of capture gamma rays as a function of borated polyethylene (BPE) inner door thickness and location of the inner door; and 3) the effect of lining the maze corner with different neutron moderating materials.

The goal of this study was to produce a novel high density concrete against neutron and photon radiations using tourmaline and galena. Materials an...
متن کاملProduction of an economic high-density concrete for shielding megavoltage radiotherapy rooms and nuclear reactors
Background: In megavoltage radiotherapy rooms, ordinary concrete is usually used due to its low construction costs, although higher density concrete are sometimes used, as well. The use of high-density concrete decreases the required thickness of the concrete barrier hence, its disadvantage is its high cost. In a nuclear reactor, neutron radiation is the most difficult to shield. A method for p...

Fast and accurate identification of neutron sources is very important in nuclear nonproliferation and international safeguards applications. Commonly, the identification of neutron spectra relies on unfolding procedures, which requires the solution of an ill-posed problem. In this paper, we present a new application of an existing technique, which can be used for neutron source identification w...
