              In this instrument:
                                     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 ten 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 ten years; or
         (c)          having clinical evidence of chronic arsenic toxicity.
                                     being exposed to lead as specified means:
         (a)          engaging in lead risk work as specified for at least two years; or
         (b)           having a blood lead level of at least 40 micrograms per decilitre; or
         (c)           having lead nephropathy.

      Note: lead risk work as specified is also defined in the Schedule 1 – Dictionary.
                                     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; or
         (c)          repairing and/or servicing diesel engines.
                                     chronic renal failure means:
         (a)          having a glomerular filtration rate of less than 15 mL/min/1.73 m2 for a period of at least three months; or
         (b)          a need for renal replacement therapy (dialysis or transplantation) for treatment of complications of decreased glomerular filtration rate which would otherwise increase the risk of morbidity and mortality; or
         (c)          undergoing chronic dialysis.
                                     chronic urinary tract infection means bacterial infection of the urinary tract that does not respond to treatment, keeps recurring over a period of at least one year or there are at least ten episodes of urinary tract infection.
                                     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 the  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
