摘　　要：理论计算结果和实测数据都说明β射线橡胶测厚仪的剂量比γ射线橡胶测厚仪大两个数量级。采用γ射线测厚仪安全可靠，对于β射线测厚仪应认真考虑其安全性。The theoretically calculated results and measured data showed that theradiation dose from &ray rubber gauge was higher than that from y--ray rubber gauge by twoorders of magnitude. It would be safe to use y--ray rubber gauge. For &ray rubber gauge,thesafety should be considered carefully.
