What is a radiation dose?
The radiation dose is the amount of radiation that the person is exposed to from a source, such as X -rays, space rays or living near the nuclear power plant. During the year, each is exposed to some radiation, but some activities may increase the level of exposure and may be a reason for concern. Determination of standardized systems for measuring absorbed radiation helps scientists and care providers to monitor radiation exposure in patients to determine whether they are at increased risk of cancer and other health problems. Sievert represents gray gamma radiation, which takes the form of an equivalent dose. Equivalent doses are useful because different radiation sources behave differently; Gray alpha radiation is very different from gray gamma radiation, for example. Each Sievent contains 100 REM. Rem is a high unit of individual exposure and measurements are often served in Milliri. Some measurements are presented in Millisievers rather than Rems and Millirems.
According to the environmental protection agency in the United States, the United States inhabitants absorb around 620 millrimers every year. Life next to a nuclear power plant can add milling doses of mills, as well as activities such as flying on long trips. Sources of radiation are very variable, but checks reduce the overall dose of radiation; For example, computer users absorb some radiation from their terminals, but it is not enough to be a health risk.
Radiation dose is a special reason for concerns about medical imaging, especially in patients who need repeated imaging studies and patients who take nuclear traces in imaging studies. These hitchhiking components use radiation on an image resolution, so the physician can identify structures of interest or concerns in the body and may pose a health risk to patients over time. Among the different initiatives to check the radiation dose with medical display are afterTaking shielding, only ordering imaging studies, if absolutely necessary, and the use of batch monitors for medical staff to identify someone who is based on the risk of health problems from the radiation exposure.
A very high dose with one radiation can kill or cause serious injuries. Radiation disease and cancer are two potential exposure results to high doses of radiation. In situations where high radiation is a problem, public health agencies use monitors to check the amount of radiation present to provide appropriate public health recommendations, including designing to evacuate or wear protective equipment.
