Abstract
(106)Ru/(106)Rh is unique amongst other commonly used beta sources such as (147)Pm, (85)Kr, (204)Tl, (32)P, (nat)U and (90)Sr/(90)Y in the sense that it is capable of simultaneously delivering shallow/skin, eye lens and deep/whole body doses (WBDs) and they differ from each other substantially. In view of this, the investigation of various quantities defined for individual monitoring is possible and this makes (106)Ru/(106)Rh beta source, a classical example in radiation protection and dosimetry. This led us to estimate skin, eye lens and WBDs for (106)Ru/(106)Rh beta source. Optically stimulated luminescence based ultra-thin α-Al2O3:C disc dosimeters were used in the present study. Typical values (relative) of the eye lens and whole body/deep doses with respective to the skin dose (100%) were experimentally measured as ~66 ± 4.6% and 17 ± 3.9%, respectively. The study shows that (106)Ru/(106)Rh beta source is capable of delivering even WBD which is not the case with other beta sources.
