As has been demonstrated throughout this radiation safety course, scientific and mathematical principals are the tools we use to determine what exactly is a safe Time or Distance as it relates to radiation exposure. The Biodex Tungsten Vial Shield (053-805) was evaluated by adding 1,428 mCi of Tc-99m into a 10 mL sterile vial.

Tungsten alloy shielding still has the same radiation shielding ability as lead even when dwindled in volume and thickness of the container. Pixel values of CR as a function of the number of TFP sheets (irradiated by 50 kVp xrays). There are two reasons: Now, lets just fast forward the scenarios above 74.3 days (the half-life of Ir-192) and now our 100 ci source has decayed to 50 ci from the original 100 ci source, all of the safety protocols and exposure times have changed. 5H2O (CMT)concentration levels (such as 5, 15, 30, and 40 weight percent) were examined to investigate the radiation protective shielding properties of poly(methyl methacrylate)/colemanite (PMMA/CMT) composite.
