Protection against ionizing radiations such that the radiation doses received by an individual from internal or external sources, or both, are as low as reasonably achievable and do not exceed the maximum levels given in Table 10.1.2[link].

Table 10.1.2| top | pdf |
Maximum primary-dose limit per quarter [based on National Health and Medical Research Council (1977[link]), as amended]

Note: The annual MPD is typically twice the quarterly MPD.

Part of bodyMPD (i)MPD (ii)
Gonads, bone marrow, whole body 30 mSv (3 rem) 2.5 mSv (2.5 rem)
Skin, bone, thyroid 150 mSv (15 rem) 15 mSv (1.5 rem)
Hands, forearms, feet, ankles 400 mSv (40 rem) 35 mSv (3.5 rem)
Organs (including eye lens) 80 mSv (8 rem) 7.5 mSv (0.75 rem)
Abdomen of female of reproductive age 13 mSv (1.3 rem) 1 mSv (0.1 rem)
Foetus between diagnosis of and completion of a pregnancy 10 mSv (1 rem)  

Note: The maximum primary dose limits as set here are advisory only, and ultimately one should strive to achieve an MPD limit as low as reasonably achievable (often referred to by the acronym ALARA), economic and social factors being taken into account.
