the particular organ or tissue. The formula used to calculate the cumulative equivalent dose allows doses from multiple types of ionising radiation to be combined, by accounting for their differing biological effect. The unit of equivalent dose is the sievert. For the purposes of this Statement of Principles, the calculation of cumulative equivalent dose excludes doses received from normal background radiation, but includes therapeutic radiation, diagnostic radiation, cosmic radiation at high altitude, radiation from occupation-related sources and radiation from nuclear explosions or accidents;
                                     hyperuricaemia means having a serum urate level persistently greater than 0.40 mmol/L.
                                     hypertensive emergency or crisis, also known as malignant hypertension, means a sudden and severe increase in blood pressure to a diastolic blood pressure greater than or equal to 110 mm Hg or a systolic blood pressure greater than or equal to 180 mm Hg, or of a sufficient degree to cause acute impairment to one or more organ systems.
                                     inhaling, ingesting or having cutaneous contact with a chemical agent contaminated by 2,3,7,8-tetrachlorodibenzo-para-dioxin (TCDD) means any of the following:
                                     (a) decanting or spraying;
                                     (b) cleaning or maintaining equipment used to apply;
                                     (c) being sprayed with;
                                     (d) handling or sawing timber treated with;
                                     (e) being in an environment shrouded in dust from timber treated with;
                                     (f) using cutting oils contaminated with; one of the following chemicals:
(i)            2,4,5-trichlorophenoxyacetic acid;
(ii)         2,4,5-trichlorophenoxypropionic acid;
(iii)       2,4,5-trichlorophenol;
(iv)        2-(2,4,5-trichlorophenoxy)-ethyl 2,2-dichloropropionate;
(v)          o,o-dimethyl-o-(2,4,5-trichlorophenyl)-phosphorothioate;
(vi)        pentachlorophenol;
(vii)     2,3,4,6-tetrachlorophenol;
(viii)   2,4,6-trichlorophenol;
(ix)        1,3,5-trichloro-2-(4-nitrophenoxy)benzene;
(x)          2,4-dichloro-1-(4-nitrophenoxy)benzene; or
(xi)        2,4-dichloro-1-(3-methoxy-4-nitrophenoxy)-benzene.
                                     ischaemic heart disease—see subsection 7(2).
                                     MRCA means the Military Rehabilitation and Compensation Act 2004.
                                     night shift work means working for at least 3 hours between 12 AM and 5 AM.
                                     non-steroidal, anti-inflammatory drug means any of a large chemically heterogeneous group of drugs that inhibit cyclooxygenase activity, resulting in decreased synthesis of prostaglandin and thromboxane precursors from arachidonic acid. In addition to anti-inflammatory actions, they have analgesic, antipyretic, and platelet inhibitory actions.
                                     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 combination of same. For pipe tobacco, cigars or combinations of multiple tobacco types, 1 gram of tobacco is considered to be equal to one cigarette.
 Note 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
