In this instrument:
                                     cumulative equivalent dose means the total dose of ionising radiation received by 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;
                                     hidradenitis suppurativa means a chronic skin disease of the terminal follicular epithelium in the apocrine gland-bearing skin (axillae, groin, and under the breasts), characterised by comedo-like follicular occlusion, chronic relapsing inflammation, mucopurulent discharge, and progressive scarring.
                                      latitude equivalent hours means hours of sunlight exposure multiplied by the appropriate latitude weighting factor as follows:
(a)          For tropical latitudes (23.5° South to 23.5° North) multiply by 1.0;
(b)          For subtropical latitudes (23.6° - 35°) multiply by 0.75;
(c)          For warm temperate latitudes (35.1° - 45°)  multiply by 0.5;
(d)          For cool temperate latitudes (45.1° - 65°) multiply by 0.25.
Note: sunlight exposure is calculated as the sum of sunlight exposure in each separate latitude, accounting for the different sunlight intensity in each latitude (weighting factor).
Sum of sunlight exposure = (hours spent in tropical latitude x tropical latitude weighting factor) + (hours spent in subtropical latitude x subtropical latitude weighting factor) + (hours spent in warm temperate latitude x warm temperate latitude weighting factor) + (hours spent in cool temperate latitude x cool temperate latitude weighting factor)
                                     MRCA means the Military Rehabilitation and Compensation Act 2004.
                                     non-melanoma malignant neoplasm of the skin—see subsection 7(2).
                                     phimosis means an inability to retract the penile foreskin over the glans penis.
                                     PUVA therapy means a combination treatment consisting of taking oral psoralen (P) (also known as Methoxsalen) and exposing the skin to long-wave ultra-violet light (UVA).
                                     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 defined in the Schedule 1 - Dictionary.
                                     sinus tract means an infected blind-ending epithelium-lined tract leading from a focus of infection to the surface of the skin.
                                     sunburn means painful erythema of the skin of at least 48 hours duration, resulting from exposure to solar ultraviolet radiation.
                                     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;
