There are many types of personal dosimeters. In Shanghai, the personal lithium-iodide personal dosimeter is mainly used. In Tianjin, powdery tubular lithium fluoride personal dosimeters are used. To find out whether the two dosimeters are in compliance with the monitoring results, June 1990 July to July the Ministry of Health commissioned in Tianjin and Shanghai personal dosimeter for a double-track comparison, our district to undertake a clinical trial of X-ray staff personal dose comparison. First, the survey method 1 object selection: Lot hospital radiation staff 40. 2. Monitoring methods: Personal dosimeters have been through the standard scale, the two dosimeters into a circular box about 2 cm in diameter, according to personal dosimeter wear requirements, the dosimeter worn on the staff’s left chest or left collar Department, the wear cycle of one month.
