Is there a safety standard for exposure to radiation?

According to the recommendations and guidance established by the ICRP (International Commission on Radiological Protection) in 1990, a dose limit for an average person is 1mSv per year, which is often referred to as a safety standard. This figure is an accumulated dose of exposure over a year and excludes natural (approx. 2.4mSV) and medical exposure such as X-ray inspection.
