The occupational exposure limit to radiation refers to the maximum amount of radiation that a person working in a radiation-exposed environment can be exposed to in a year without any adverse health effects. Option B, which is 50mSv/yr, is the recommended limit set by the International Commission on Radiological Protection (ICRP) for occupational exposure. This limit was established based on extensive research and studies on the health effects of radiation exposure over extended periods of time. Therefore, options A, C, and D, which are 20mSv/yr, 100mSv/yr, and 10mSv/yr, respectively, are incorrect as they either fall below or exceed the recommended limit and may pose potential health risks to workers in radiation-exposed environments. It is important for employers to ensure that workers are not exposed to levels of radiation above the recommended limit and to implement appropriate safety measures to minimize any potential risks.
