According to CHOP Radiation Safety Manual , all persons (personnel or attendants of the patient) must compulsorily wear leaded aprons during an exposure. The personnel should wear leaded glasses and thyroid shield to reduce the exposure of eye lenses and thyroid gland to scattered radiation…
Just like in other facets of the society, medical imaging has established distinctive rules and regulations that guide the behavior of the practitioners at various stages. In this respect, it is worth appreciating that radioactivity is very dangerous and medical implications are unbelievably adverse.
Their information campaign not only serves as an awareness and educational demonstration, it also seeks to instigate change on the attitudes and values practiced by the medical groups and allied professionals involved in the implementation of CT scan. Indirectly, it gives further data to interested parents and family members; providing them the full picture on the impact generated by CT scans on vulnerable pediatric groups and the factors increasing such events.
Imaging with the help of Magnetic Resonance Imaging, Computerized Tomography, Positron Emission Tomography and similar ones-has become very much popular and is in wide spread use-even in developing countries. The evolution of these techniques has been the outcome of the various drawbacks associated with older techniques like Nasal Radium Irradiation and others-which have had their effects-often irreversible, on the people on which they were used.
Artificially, these rays are produced by backlights, fluorescent lights and electric arcs such as those produced during welding. UV rays have many substantial effects and damages to both living things and the materials. It triggers chemical reactions, causes substances to grow and causes sun burn to people.
This plastic-mounted film is wrapped in thin, light-tight paper, sandwich fashion and placed in a plastic holder. The holder clips onto the wearer's clothing, enabling the film badge to give a measure of total, or whole body, air kerma (exposure). The plastic case usually contains a cut-away portion to allow the entrance of beta particles or other electrons.
Radiation is used by health care industry for many purposes like UV rays for disinfection, x-rays for imaging etc. Every time radiation is used by any instrument, the intensity and time of exposure to the particular type of radiation have to be determined to make sure to reduce the ill effects of over dosage of radiation.
The first could be from exposure to the sun responsible for cosmic radiation as a result of solar flares. I could also be exposed to radon gas from enclosed environments such as home known to emit the radioactive alpha
