For pipe tobacco, cigars or combinations of multiple tobacco types, 1 gram of tobacco is considered to be equal to one cigarette.\n\nNote 2: Pack-years are calculated by dividing the number of cigarettes smoked per day by 20 and multiplying this number by the number of years the person has smoked. For example, smoking 10 cigarettes per day for 10 years is equal to 5 pack-years, and smoking 40 cigarettes per day for 10 years is equal to 20 pack-years.\n\n                               ppm-years means parts per million multiplied by years of exposure.\n\n                               relevant service means:\n\n(a)          operational service under the VEA;\n\n(b)          peacekeeping service under the VEA;\n\n(c)          hazardous service under the VEA;\n\n(d)          British nuclear test defence service under the VEA;\n\n(e)          warlike service under the MRCA; or\n\n(f)           non-warlike service under the MRCA.\n\nNote: MRCA and VEA are defined in the Schedule 1 - Dictionary.\n\n                               terminal event means the proximate or ultimate cause of death and includes the following:\n\n(a)           pneumonia;\n\n(b)           respiratory failure;\n\n(c)           cardiac arrest;\n\n(d)           circulatory failure; or\n\n(e)           cessation of brain function.\n\n                               VEA means the Veterans' Entitlements Act 1986.\n\n \n\n \n","sortOrder":0}],"analysis":{"flash_summary":{"complexity_score":7,"scope_assessment":{"changed":true,"description":"This instrument expressly repeals the 2015 Statement of Principles (s4) and replaces it with updated definitions (s7, Schedule 1) and an expanded set of qualifying factors (s9) including newer drug classes (PARP inhibitors), specified chemical thresholds (benzene, styrene, formaldehyde), obesity, HIV, transplantation, and clarified radiation dose rules (Schedule 1).
