Beautiful Wallpaper ideas For One Year background Radiation Exposure

The natural background radiation from cosmic and earth sources is not harmful to humans. However, one year’s worth of exposure is dangerous enough to pose health risks. That’s why it is vital that airport screening devices be tested for safety. An x-ray machine’s safety measures should protect the operator and passengers. This is a crucial step in ensuring the security of travelers. The U.S. Food and Drug Administration (FDA) has the authority to set standards for x-ray systems.

A millisievert is a measure of the average yearly radiation dose in the United States. One millisievert is equivalent to one milligray (mG) of radiation. This level is equal to one rad or rem if the person had a background dose of one rem per year. The historical system of dosimetry equates one rem to one rad. This value is a measure of how much radiation we are exposed to without doing any harm to our health.

How Much Radiation Does a Person Get in a Year?

 

A millisievert (mSv) is the average amount of radiation received by Americans over the course of a year. It is the same as a milligray (mG) of radiation. The historical system of dosimetry equates one mSv to a rem, the amount of radiation that affects the body. Although a mSv dose does not cause harm to the body, a background dose greater than 620 milliSv is harmful to the health of an individual.
