In this instrument:
                                  acute precipitating event means a physical or psychological stimulus or event that causes a sudden, intense psychological or physical response.
Note: Examples of an acute precipitating event include:

           (a)                                                   abrupt cessation or lowering of anti-thyroid therapy;
           (b)        acute illness such as acute myocardial infarction, stroke and congestive heart failure;
           (c)         acute iodine load;
           (d)        experiencing an acute, severe, emotional stressor;
           (e)         infection;
           (f)         parturition;
           (g)       physical trauma or injury; and
           (h)        surgery.
                                  cumulative equivalent dose means the total dose of ionising radiation received by the particular organ or tissue from external exposure, internal exposure or both, apart from normal background radiation exposure in Australia, calculated in accordance with the methodology set out in Guide to calculation of 'cumulative equivalent dose' for the purpose of applying ionising radiation factors contained in Statements of Principles determined under Part XIA of the Veterans' Entitlements Act 1986 (Cth), Australian Radiation Protection and Nuclear Safety Agency, as in force on 2 August 2017.
         Note 1: Examples of circumstances that might lead to exposure to ionising radiation include being present during or subsequent to the testing or use of nuclear weapons, undergoing diagnostic or therapeutic medical procedures involving ionising radiation, and being a member of an aircrew, leading to increased levels of exposure to cosmic radiation.
         Note 2: For the purpose of dose reconstruction, dose is calculated as an average over the mass of a specific tissue or organ. If a tissue is exposed to multiple sources of ionising radiation, the various dose estimates for each type of radiation must be combined.
                                  goitre—see subsection 7(2).
                               iodine deficiency means:
(a)          an average intake of iodine of less than 150 micrograms of iodine per day, or less than 250 micrograms per day for pregnant or lactating women, for a continuous period of at least 30 days; or
(b)          having a urinary iodine concentration of less than 100 micrograms per litre, or less than 150 micrograms per litre for pregnant women.
                                  iodine excess means:
(a)           an average intake of more than 1,100 micrograms of iodine per day for adults, or more than 900 micrograms per day for those aged 18 years and under, for a continuous period of at least 3 months; or
(b)          having a urinary iodine concentration of greater than 300 micrograms per litre, or greater than 500 micrograms per litre for pregnant women.
                                  MRCA means the Military Rehabilitation and Compensation Act 2004.
                                  one pack-year means the amount of tobacco consumed in smoking 20 cigarettes per day for a period of 1 year, or an equivalent amount of tobacco products.
         Note 1: An equivalent amount of tobacco products is 7,300 grams of smoking tobacco by weight, either in cigarettes, pipe tobacco or
