Calculations on shielding are required for the building of a gamma ray radiography exposure room to ensure worker radiation. A measurement used evaluate radiation diffusive and absorption characteristics medium is linear attenuation coefficient ( ). Despite fact that, as moves through medium, its influenced by wavelength well thickness composition crucial in interaction with matter. This resear...

Shielding the radiosensitive gonads during X-ray exposure has been advocated for plain film radiography for many years. In the UK, gonad shields are not widely employed in routine CT scanning, possibly owing to a perceived difficulty in protecting the gonads from a multidirectional X-ray source. The increasing numbers of CT scanners in the UK, with the large doses they deliver to patients, make...

The 250kW TRIGA Mark II research reactor, Vienna, is equipped with experimental facilities inside and outside the reactor core. Outside the core, there are four beam tubes (three radial and one tangential beam tube), a thermal column and a neutron radiography collimator, supplying neutrons for irradiation experiments. These experiments include neutron radiography, neutron tomography, neutron ac...

Abstract Regarding porosity formation and gas content, choosing the appropriate shielding for laser welding is essential achieving high-quality joints. Keyhole-induced tendency nitrogen content in SS 304 stainless steel welds were investigated based on gases during fiber welding. Beads-on-plate autogenous made at 5 kW continuous wave (CW) N 2 Ar mixtures. Optical metallography, micro-focused X-...

background: gonad shielding has been recommended during pelvic x-rays since the 1950s. the popular method of gonad shielding is placement a lead shield in the midline of the pelvis. the aim of this study was to evaluate the prevalence and utility of gonad shielding in pediatrics undergoing pelvic x-rays.materials and methodsfollowing study approval, we retrospectively retrieved data from the di...
