What is the annual effective dose limit for the general public assuming infrequent exposure?

The correct answer is based on established radiation safety guidelines that govern exposure limits for members of the general public. When considering infrequent exposure, the annual effective dose limit is set to ensure that individuals are protected from potential health risks associated with radiation.

The limit of 1 mSv is commonly adopted as the dose for continuous exposure, such as in occupational settings or for populations that might experience regular radiation exposure. However, for infrequent exposure scenarios, the permitted limit is generally higher, reflecting a balance between safety and practical considerations in emergency situations or infrequent medical radiography.

The value typically recognized for infrequent exposure aligns with the 5 mSv limit, which is considered to be manageable in terms of both health risk and practical exposure situations. Hence, this limit allows for certain exceptions without compromising overall public safety.

Regarding the other options, 2 mSv and 10 mSv exceed the typical limits set for infrequent exposure scenarios under international safety guidelines, while 1 mSv is more applicable to continuous exposures rather than infrequent ones. Understanding these standards is critical for those working within fields involving radiation to ensure safety protocols align with health regulatory recommendations.
