Training is not required. General information is available on demand through the web-based course “Working Safely Near Radioactive Materials EHS-5275-WEB“. A 0.5-mm thick lead apron reduces scattered radiation by approximately 10 times c. Doubling the distance between a person and the radiation source reduces the radiation exposure by a factor of 4 d. Before you attempt a procedure, think ahead how you will accomplish it 15. Radiation Health Effects. Ionizing radiation. has sufficient energy to affect the atoms in living cells and thereby damage their genetic material (DNA). Fortunately, the cells in our bodies are extremely efficient at repairing this damage. However, if the damage is not repaired correctly, a cell may die or eventually become cancerous.

Radiation only event with high risk of contamination (and non-radiation hazards have been excluded): e.g., Radiological Dispersal Device (RDD) First receivers delivering care to victims more likely to be externally contaminated: i.e., healthcare providers working in pre-decontamination (triage) and decontamination areas 15, 16, 19Sep 8, 2008 · Anyone working with radiation and likely to receive a dose of more than 100 millirem a year must receive training about how to protect themselves, according to NRC regulations. Duke University estimates staff working on units at Duke University Medical Center where radiation is used can expect to receive less than 200 millirem per year. 1910.1096 (a) (7) Rem means a measure of the dose of any ionizing radiation to body tissue in terms of its estimated biological effect relative to a dose of 1 roentgen (r) of X-rays (1 millirem (mrem)=0.001 rem). The relation of the rem to other dose units depends upon the biological effect under consideration and upon the conditions for ... For reducing radiation exposure, there are 3 principals: time, distance, and shielding. Go to: 1. Time. Radiation exposure can be accumulated over the time of exposure. In C-arm fluoroscopy guided interventions, the time spent checking the C-arm fluoroscopy is related to the radiation exposure.
