  In this instrument:
                                     8-hour time-weighted average means the averaging of different exposure levels to benzene during an average exposure period equivalent to 8 hours.
                                     being exposed to benzene as specified means:
(a)          having cutaneous contact with liquids containing benzene greater than 1% by volume; or
(b)          ingesting liquids containing benzene greater than 1% by volume; or
(c)          inhaling benzene vapour where such exposure occurs at an ambient 8‑hour time-weighted average benzene concentration exceeding 5 parts per million.
Note: 8-hour time-weighted average is also defined in the Schedule 1 - Dictionary.
                                     being:
      (a) on land in Vietnam; or
(b) at sea in Vietnamese waters;
means service in at least one of the areas and at the times described in Items 3A, 3B, 4 and 8 of Schedule 2 of the Veterans' Entitlements Act 1986.
Note: VEA is also defined in the Schedule 1 - Dictionary.
                                     being overweight or obese means having a Body Mass Index (BMI) of 25 or greater.
Note: BMI is also defined in the Schedule 1 - Dictionary.
                                     BMI means W/H2 where:
(a)          W is the person's weight in kilograms; and
(b)          H is the person's height in metres.
                                     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.
                                     estuarine Vietnamese waters means at least one of the waterways or harbours in the relevant areas described in Items 4 and 8 of Schedule 2 of the
                                     VEA.
Note: VEA is also defined in the Schedule 1 - Dictionary.
                                     inhaling, ingesting or having cutaneous contact with a chemical agent contaminated by 2,3,7,8-tetrachlorodibenzo-para-dioxin (TCDD) means:
(a)          decanting or spraying;
(b)          cleaning or maintaining equipment used to apply;
(c)           being sprayed with;
(d)           handling or
