If fluoro times indicate possibility that skin entry dose may have exceeded 100 Rads, procedure must be reviewed in detail to determine max skin entry dose. There is no single correct answer for all situations, and in certain countries there may even be specific regulations. This way imaging professionals help ensure that both occupational and nonoccupational dose limits, that result in a negligible risk of bodily injury or genetic damage, will remain in well below maximum allowable. These subatomic particles are ejected from atoms at very high speeds. - Low-Dose mode: 40% dose of Normal fluoro - means to reset display at zero for new exam/procedure Protecting the patient. Radiation protection of the patient does not mean that this dose should be minimized, but instead that the irradiation should be optimized so that the correct . Figure 6-10 Target-surface distance.

Both the radiographer and the radiologist share in keeping the patient medical radiation exposure at the lowest level possible. The patient's date of conception or date of LMP (last menstrual period) should also be determined. X-ray Tube Position Position the X-ray tube under the patient not above the patient. Early Non-Stochastic Few hours or days after a very high level radiation exposure to the body Redness on the skin (erythema) Decrease in white blood cell count. If a calculation of radiation dose is required in order to advise the patient, the radiographic factors should be noted if known. Tap here to review the details. - Source to Skin Distance (SSD): Some of the main methods for minimizing the dose to the fetus include: For well performed procedures, estimated fetal doses are typically quite small, and well below the level of concern for radiation effects. Summarize the radiation protection methods for the radiographer. Examples of internal radionuclides are: Potassium- 40, Carbon-14, Hydrogen-3 (Tritium), and Strontium-90 An average individual receives approximately 67mrem per year from combined exposure to radiations from the earths surface and radiation within the human body.
