ABSTRACT
Objective In order to test and improve the monitoring technical level and ability of radiation environmental monitoring network in Zhejiang Province, ensure the accuracy and reliability of monitoring data and information, and obtain the cosmic ray response values of instruments and equipment in this year. Methods In September 2018，an intercomparison meeting of environmental gamma radiation air absorbed dose rate within the radiation environmental monitoring network of Zhejiang province was held in Ningbo，which was organized by Zhejiang Province Radiation Environmental Monitoring Center.A total of 33 sets of instruments from 15 member units participated in the intercomparison measurements at 5 environmental measuring points, and the comparison results were evaluated by the Z score values. Results It was found that the |Z| of all measurement results were less than or equal to 2, and the evaluation results were satisfactory and acceptable. Conclusion The measured data of scintillation counters have relatively wider dispersion，and the high pressure ionization chambers have bigger response valuetocosmic ray. The measurement results of the two kinds of instruments keep a good linearity except for the measurement points of cosmic ray response.
ABSTRACT
Objective:To compare and analyze the changes and the influencing factors of out of pocket(OOP) expenditure before and after the new medical reform.Methods:2000-2015 time series data was used to compare the changes of OOP in different years.The cross-section data was applied to compare the OOP of China and other countries.The principle component analysis method was used to research the contribution rates of different factors for the OOP ratio changes.Result:According to the vertical comparison,it found that the OPP ratio showed steady decreasing trend.The horizontal comparison found that there were great gap for OOP ratios of China and other countries.The per capita GDP,under five mortality and proportion over 65 years were significant factors for OOP.Conclusion:The OOP ratio still needed to be devreased,which needed to promote the economic growth,implement medical insurance system,improve the public health input and decrease the health economic burden for residents.
