In this instrument:
                                     8-hour time-weighted average means the averaging of different exposure levels to ethylene oxide during an average exposure period equivalent to eight hours.
                                     being obese means:
                                     (a)               having a Body Mass Index (BMI) of 30 or greater; or
                                     (b) for males, having a waist circumference exceeding 102 centimetres; or
                                     (c) for females, having a waist circumference exceeding 88 centimetres.
Note: BMI is 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.
                                     having been exposed to second-hand smoke means having been in an enclosed space and inhaling smoke from burning tobacco products or smoke that has been exhaled by another person who is smoking.
                                     malignant neoplasm of the breast—see subsection 7(2).
                                     menopausal hormone therapy means administration of estrogen preparations, often in combination with a progestogen, to offset a hormone deficiency following surgically induced or naturally occurring menopause.
                                     MET means a unit of measurement of the level of physical exertion. 1 MET = 3.5 ml of oxygen/kg of body weight per minute, or 1.0 kcal/kg of body weight per hour, or resting metabolic rate.
                                     MRCA means the Military Rehabilitation and Compensation Act 2004.
                                     nulliparous means having never given birth to a viable infant.
                                     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 cigars, or a
