  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.
                                  acute lymphoblastic leukaemia/lymphoblastic lymphoma—see subsection 7(2).
                                  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 five parts per million.
     Note: 8-hour time-weighted average is also defined in the Schedule 1 - Dictionary.
                                  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.
                                  MRCA means the Military Rehabilitation and Compensation Act 2004.
                                  organ or tissue transplantation means:
         (a)          the transplantation of all or part of an organ or tissue; or
         (b)          the transplantation of a substance obtained from an organ or tissue.
                                  ppm-years means parts per million multiplied by years of exposure.
                                  relevant service means:
         (a)          operational service under the VEA;
         (b)          peacekeeping service under the VEA;
         (c)          hazardous service under the VEA;
         (d)          British nuclear test defence service under the VEA;
         (e)          warlike service under the MRCA; or
         (f)           non-warlike service under the MRCA.
Note: MRCA and VEA are also defined in the Schedule 1 - Dictionary.
                                  terminal event means the proximate or ultimate cause of death and includes the following:
         (a)           pneumonia;
         (b)           respiratory failure;
         (c)           cardiac arrest;
         (d)           circulatory failure; or
         (e)           cessation of brain function.
                                  VEA means the Veterans' Entitlements Act 1986.
