In this instrument:

                                     acute silicosis means a pulmonary disease characterised by basilar filling of alveoli with lipid and proteinaceous exudative material, following exposure to high levels of respirable crystalline silica dust over a short time span.

                                     ambient, chronically polluted air as specified means air with average annual concentrations of:
            (a)          particulate matter with an aerodynamic diameter of < 2.5 µm (PM2.5) exceeding 15 µg/m3; or
            (b)          particulate matter with an aerodynamic diameter of < 10 µm (PM10) exceeding 25 µg/m3.
                             being exposed to arsenic as specified means:
(a)          consuming drinking water with an average arsenic concentration of at least 50 micrograms per litre for a cumulative period of at least 10 years; or
(b)          consuming drinking water resulting in a cumulative total arsenic exposure equivalent to having consumed drinking water containing at least 50 micrograms per litre for at least 10 years; or
(c)          having clinical evidence of chronic arsenic toxicity.
                             being heavily exposed to diesel engine exhaust means:
(a)          being an occupant in an enclosed diesel powered vehicle cabin contaminated with diesel fumes; or
(b)          working in an enclosed space where diesel powered engines or motors are being operated.
                             berylliosis means acute or chronic beryllium disease involving the lungs. Acute beryllium disease is a rapid onset form of chemical pneumonitis (severe inflammation of the lung) that results from breathing high airborne concentrations of beryllium. Chronic beryllium disease is induced by a delayed hypersensitivity reaction to beryllium fumes and is characterised by the formation of granulomas within the lung, and may progress to fibrosis of the lungs.
                             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
