title: [Research on the dose-response relationship of hand transmitted vibration and its hygienic standard].
abstract: According to ISO 5349-1986, the akw(4) was 9.04-41.47m/s2 which was measured and calculated in 5 types of instruments: chain saw, cleaner, rock driller, riveter & emery wheel. There were 170 cases with white finger through epidemiologic investigation on 5 types of workers in 1,675 persons. Based on the work mentioned above, a formula, which represented worker cumulative exposure to vibration was deduced: D = [(a2kw(4).T)1/2.Y.d]2 Furthermore, the dose-response relationship of hand transmitted vibration and prevalence of white finger was computed, the regression equation was: P = 1.0904X - 6.214 2 Under precondition of exposure to vibration for 20 years with 90% of workers having no white fingers, the limit of hygienic standard of hand transmitted vibration in china should be set at 4 hours and as akw(4) less than or equal to 5 m/s2 based on the regression equation.
