Abstract:	世界各地對不同工作者的流行病學研究顯示，全身振動暴露與背部疼痛以及退化性／突出性椎間盤疾病的發生有關聯，長時期暴露於全身振動增加罹患脊椎與神經方面疾病的機率。流行病學的研究結果促使歐盟國家比利時於1978年、德國於1993年、荷蘭於1997年、法國於1999年及日本於1980年等國家的勞工部將振動引起的脊椎病變列為職業病。在全身振動暴露評估之規範中以ISO2631/1-1985、BS6841(1987)、ANSI-1979、ACGIH及ISO2631/1-1997等規範最為各界所參考，但所建議之頻譜加權及評估方式有相當的差異，如此所建立的職業病認定基準會有相當的落差，造成對罹患職業性脊椎病變的勞工權益受損，因此有必要對各種車輛振動以不同國際規範來比較其暴露限值，進而檢討現行法規修訂之可行性。本研究之目的在比較各先進國家規範對全身振動暴露危害評估，以建立可行之振動暴露劑量計算模式。計畫之內容包括：分析各國際規範對全身振動之量測與評估、利用現有儀器設備量測不同車輛行進時之振動量，其目標在利用不同標準評估每天容許全身振動暴露劑量比較不同規範對全身振動暴露之評估結果差異性、並建立可行之振動暴露劑量計算模式。 Epidemiological studies have indicated that long-term exposure to occupational whole-body vibration (WBV) is associated with the risk of degeneration intervertebral discs of the spine and low back pain. The results of epidemiological studies accelerate the labor department of the Belgium, Germany, Holland, France and Japan to set regulation to control WBV to reduce the spinal column disorders induced by WBV as an occupational disease in 1978, 1993, 1997, 1999 and 1980 respectively. There are couples of recommendations for exposure evaluation, such as ISO 2631/1(1985), BS 6841(1987), ANSI(1979), ACGIH(1979) and ISO 2631/1(1997), however, the frequency weightings and evaluation methods proposed by these suggestions are quite different. So, it is necessary to compare the exposure limits adopted by these different countries. The objectives of the study are to compare the evaluation procedures of WBV and to establish the model of exposure dose for domestic regulations. The study is going to (1) analyze the discrepancies among the regulation of ISO 2631and other countries (2) to measure the vibration dose of different vehicles and (3) to establish a suitable model for evaluating the exposure dose of WBV for domestic usage.
