What is the expected maximum dose for the general public regarding XRF?

The expected maximum dose for the general public regarding X-Ray fluorescence (XRF) is 0.2 rem per year. This standard is based on recommendations from regulatory bodies that aim to minimize radiation exposure to individuals not involved in occupational exposure. The limit is set to ensure safety and health, preventing potential adverse effects of radiation such as cancer or other health risks.

It's important for regulations to establish a conservative approach to ensure the general public is well protected from unnecessary exposure, while allowing some level of exposure that is deemed acceptable based on scientific assessments. The threshold of 0.2 rem per year is considered a balance between allowing useful applications of XRF technology for purposes like lead risk assessment and safeguarding public health.
