![]() ![]() A lead (or lead equivalent) apron is a protective garment which is designed to shield the body from harmful radiation, usually in the context of medical imaging. The radiation records an image on photographic film or a special detector. The contrast resolution of the radio-graph represents the relative differences in receptor exposure across the image and has two primary com-ponents, subject contrast and display contrast. Lead aprons are used in medical facilities to protect workers and patients from unnecessary x-ray radiation exposure from diagnostic radiology procedures. The machine produces a small burst of radiation that passes through your body. CT emits a powerful dose of radiation, in some cases equivalent to about 200 chest X-rays, or the amount most people would be exposed to from natural sources over seven years. The technologist carefully aims the x-ray beam at the area of interest. Very high doses of radiation cause damage to human cells, as evidenced by skin burns, loss of hair, and increased incidence of cancer. When X-ray radiation is absorbed within our bodies, it can damage molecular structures and potentially cause harm. ![]() X-rays pass through most objects, including the body. Weighing the Radiation Risks of CT, X-ray and Other Imaging. There are no published scientific experiments studying the impact of radiation on a fetus for ethical reasons. ![]() The impact of radiation on the developing fetus is largely based on the observations made in scientific studies. no individual shall be used routinely to hold film or patients such holding shall be permitted only in very unusual and rare situations in those cases where the patient must hold the film, except during intra-oral examinations, any portion of the body, other than the area of clinical interest, struck by the useful beam shall be protected by not less than 0.5 millimeter lead equivalent material and each facility shall have leaded aprons and gloves available in sufficient numbers to provide protection to all personnel who are involved with x-ray operations and who are otherwise not shielded. X-rays are a form of radiation like light or radio waves. Yes, X-rays pose a risk to the unborn child, but only when the fetus is exposed to high enough radiation levels. Q: What is the rule concerning the holding of patients during x-ray examination?Īnswer: When a patient or film must be provided auxiliary support during a radiation exposure: 1) Mechanical holding devices shall be used when the technique permits. 2) If a human holder must be utilized: Written safety procedures, as required by RH-1602.a.4., shall indicate the requirements for selecting a holder and the procedure the holder shall follow the human holder shall be protected as required by RH-1602.a.5. ![]()
