Taking GC-2000 ion migration gas chromatograph from Chengdu Keyida Automation Co.,ltd as an example,this article analyzed the application of tritium in gas chromatography experiment and the ionizing radiation environmental impact through the monitoring data.
By using field monitoring method,this paper attempted to test backward-electromagnetic field and to analyze distribution rule of backward-electromagnetic field with empirical data collected from five base stations,namely,the Tumour Hospital of Chengdu,Shuangliu Xiaoba Village;Shanghui Building,Cheng-Yu Freeway Toll Gate,and Research Institute of Agricultural Machine.The results demonstrated tat electromagnetic radiation power generated in base station was inversely proportional to the distance of antenna.It also presented a secured 0.5-meter prevention distance of backward-electromagnetic radiation of the generated in base station,which was lower than the prevention volume of 0.08w/m2 widely accepted in accordance with Regulations for electromagnetic radiation protection and Electromagnetic Radiation Monitoring Instruments and Methods.
In this paper the status of flushing techniques and devices used in the remediation of contaminated soils were introduced.Especially their application for soils contaminated by organic matter,heavy metals and radionuclides were reviewed and evaluated.The development trend of flushing technology and its application prospect in soil remediation were also discussed.
