同时比较了两个地点的人体太阳紫外线暴露量，以研究环境因素和人的态度对个人紫外线暴露量的影响。研究于1996年10月29日在澳大利亚昆士兰州的图文巴（南纬27.5度，东经151.9度）和布里斯班（南纬27.4度，东经153.1度）进行。从位于图文巴和布里斯班的校准环境紫外线监测站收集的数据来看，从澳大利亚东部标准时间（EST）07：00到10：00，图文巴比布里斯班多接收到68%的UVA（320-400 nm）和61%的UVB（280-320 nm）。从东部时间10：00到17：00，图文巴接收到的UVA比布里斯班多5%，UVB少20%。通过测量佩戴聚砜剂量计的人类受试者的个人紫外线暴露，加强了紫外线站记录的高环境紫外线水平。与通常认为人体的紫外线暴露在海滩附近较高（即，沿海地区）比内陆地区，内陆城市图文巴（布里斯班以西127公里）每个受试者胸部和肩部的平均辐射加权紫外线暴露量比沿海城市布里斯班从东部时间07：00到17：00高30%。证据也提出了海拔高度，气候条件，人类的态度，和个人暴露于紫外线辐射的水平之间的关系。
A simultaneous comparison of human exposure to solar ultraviolet radiation at two locations was performed to study the effect of environmental factors and human attitudes on personal ultraviolet exposure. The study took place on 29 October 1996 in Toowoomba (27.5 degrees S, 151.9 degrees E) and Brisbane (27.4 degrees S, 153.1 degrees E), Queensland, Australia. From the data collected by calibrated ambient ultraviolet monitoring stations located in Toowoomba and Brisbane, Toowoomba received 68% more UVA (320-400 nm) and 61% more UVB (280-320 nm) than Brisbane from 07:00 to 10:00 Australian Eastern Standard Time (EST). From 10:00 to 17:00 EST Toowoomba received 5% more UVA and 20% less UVB than Brisbane. High ambient ultraviolet levels recorded by ultraviolet stations were reinforced by measurement of the personal ultraviolet exposure of human subjects wearing polysulfone dosimeters. Contrary to the common belief that the ultraviolet exposure to the human body is higher near the beach (i.e., coastal areas) than the inland area, the average erythemal weighted ultraviolet exposure on the chest and shoulder of each subject in the inland city of Toowoomba (127 km to the west of Brisbane) was 30% higher than in the coastal city of Brisbane from 07:00 to 17:00 EST. Evidence is also presented to suggest a relationship between altitude, climatic conditions, the human attitude, and the level of personal exposure to ultraviolet radiation.
