Final answer:
Radiation dose limits are categorized by low, moderate, and high doses, with specific limits set for whole-body and individual organ exposure. Regulations guide these limits, which vary depending on the type of exposure and the demographic affected, such as general public versus nuclear workers.
Step-by-step explanation:
Reportable dose radiation limits vary based on the part of the body exposed to ionizing radiation. For the whole body, a dose less than 100 mSv (10 rem) is considered a low dose, doses from 0.1 Sv to 1 Sv (10 to 100 rem) are deemed moderate, and anything over 1 Sv (100 rem) is considered a high dose. For an individual organ or variable organ, the dose limit can differ, often being higher than for whole-body exposure, as the threshold for causing damage is organ-specific and relates to the radio-sensitivity of the tissue.
The complete body limit is typically the same as for the whole body, encompassing all tissues and organs. Regulations such as those by the Nuclear Regulatory Commission (NRC) establish dose limits for different scenarios, such as occupational exposure for nuclear workers compared to the public.
