Radiation Safety Practice Exam

What is the annual dose limit for occupationally exposed adults?

1. 10 mREM

2. 50 mREM

3. 500 mREM

4. 5000 mREM

The correct answer is: 500 mREM

The annual dose limit for occupationally exposed adults is set at 5000 mREM (5 REM). This standard is established by regulatory agencies such as the Nuclear Regulatory Commission (NRC) and the Occupational Safety and Health Administration (OSHA) to ensure that workers in radiation-related jobs are adequately protected from the harmful effects of radiation exposure. This limit is based on extensive research into the effects of ionizing radiation and aims to minimize any potential health risks associated with routine occupational exposure. It acknowledges that while there are risks associated with exposure to radiation, the specified limit allows for necessary work within controlled environments, where safety protocols are in place to protect workers while still enabling them to perform their duties effectively. The 5000 mREM limit represents a balance between safety and practicality in professions such as healthcare, nuclear power, and research, where some level of radiation exposure is often unavoidable. Compliance with this limit is critical for maintaining a safe work environment and ensuring that individuals do not accumulate exposures that could lead to long-term health issues.
