Investigation of neutron shielding properties depending on number of boron atoms for colemanite, ulexite and tincal ores by experiments and FLUKA Monte Carlo simulations

Neutron Radiation Tests about FeCr Slag and Natural Zeolite Loaded Brick Samples

“…After dose transmission values were obtained, we applied (2) to calculate neutron total macroscopic cross sections, Σ for each samples [17][18][19][20][21]:…”

Thermal stability and high-temperature behavior of the natural borate colemanite: An aggregate in radiation-shielding concretes

“…The use of colemanite concrete proved to be an easier and more effective solution than distributing gamma shields (e.g. lead blocks) within neutron absorbing materials, such as paraffin [22][23]. In presence of high-energy gamma-and X-ray sources, the lower atomic number of elements constituting colemanite concrete represents a further advantage with respect to lead shields, in particular in the pair production and Compton scattering regions [17,24].…”

Neutron shielding qualities and gamma ray buildup factors of concretes containing limonite ore

“…Kase et al (2003) researched shielding properties of concrete samples comprise of about 80 percent by weight of oxygen and silicon. There are also some further studies on neutron-shielding properties of different materials such as polymer (Sundar et al, 1996;Harrison et al, 2008), ore (Korkut et al, 2012;Okuno, 2005) and paraffin wax (Ghassoun and Senhou, 2012). Today, gamma radiation is used in many different fields such as medical diagnosis, nuclear medicine, nuclear industry, radiation technology, scientific researches etc.…”
