• Description:
  There is an ever increasing use of modern imaging technologies which use ionizing radiation that have revolutionized diagnostic radiology. The benefits to patients however, come at a cost of chronic and cumulative exposure to clinicians. In fact, radiation exposure and spine complications, accompanied with back pain, are considered to be occupational hazards for interventionalists. Government agencies like the NIH, FDA and NCI have raised alarms about radiation exposure rising to epidemic levels. We have demonstrated the feasibility of effective 0.5 mm lead-equivalent radiation protection, at about 50% of the weight of lead-based materials, with our novel bi-layered thin film attenuating materials. These bi-layers were made using non-toxic and heavy metal-free BaSO4 and Bi2O3 compounds. We have also developed theoretical framework that predicts that the bi-layered material may be more effective at attenuating the lower energy, more biologically harmful radiation than previously possible.
