多年来，IIP－1025型放射性同位素密度计已成批地用于各工业部广1，该密度计具有的计量参数较高，但也存在一些不足，这与存在转动机械另件、必须使用两个γ射线源、主射线源的放射性强度较高、工艺参数（质量、外形尺寸）较低，以及元部件陈旧有关系。苏联有色金属自动化股份 Over the years, IIP-1025-type radioisotope density meter has been used in batches of various industries Guang 1, the densitometer has a higher measurement parameters, but there are some shortcomings, which exist with the rotating parts, you must use two A gamma ray source, the main radioactive source radiation intensity is higher, the process parameters (quality, dimensions) lower, and the relationship between the aging components.
