Transmission, buildup factors, and photon shielding capacity of vanadium reinforced tellurite glasses

“…The Z eff is a shielding factor which used to describe the shielding material as its equivalent element. For a glass material consists of i th constituent elements, the Z eff can be calculated using Equation (7).…”

“…Pure lead (Pb) and Pbbased composite have toxicity and cost related issues [1,2]; concrete suffers from unstable and cracking features due to thermal changes which leads to changes in its chemical (hydrogen) content [3]; uranium on its own is radioactive. Thus, research into novel materials such as glasses very attractive to research community to be applied as radiation shields [4][5][6][7][8][9][10][11][12][13][14].…”

“…The HVL on the other hand is the thickness of the absorbing layer required to produce a photon transmission (T) of 50% while, the MFP of a photon of specific energy is the mean distance it travels between collisions within an absorbing medium. These parameters can be obtained from corresponding values of MAC according to equations [22][23][24][25][26][27][28][29][30][31][32][33].…”

“…Today, many traditional shielding materials such as lead, concrete, depleted uranium, and many more are used for radiation shielding purposes. However, they do not provide adequate shielding requirement in new and emerging technology involving the use of radiation applications [21][22][23][24][25][26]. This is due to the sophistication in properties that is required in today's shielding material coupled with environmental concerns.…”

“…This has made bismuth (Bi)-based glasses an alternative choice for radiation shielding due to its high density just like lead it possess good photon shielding efficiency. A glass system containing a combination of Pb and Bi will in no doubt be much more effective for radiation shielding purposes [22,25]. In order to satisfy the toxicity concern of users, Pb content of such glasses should be lower compared to the Bi content.…”
