Objectives:Describes the status of nuclear and radiation safety supervision facilities in Suzhou City, analyze the existing problems; In order to enhance nuclear and radiation facilities supervise and management in Suzhou City, to protect the workers that engaged in radiation work and the public health and safety, protection of the environment, promote the application and development of nuclear and radiation technology; to implement the national radiation safety and health regulations and standards, further intensify supervision and management of radiological health, specification management employer of radiological health, Improve self-management levels of radiation work units, improve the overall management of radiation health, provide management expertise for the relevant units and personnel,for health administrative departments to understand the city’s radiation health management、 strengthen macro guidance of this work and decision-making provide a reliable basis, explore measures to strengthen and improve the management of radiological health. Promote the healthy development of China’s science and technology of radiation cause. Better protect public health and the prevention of environmental pollution.Methods:Arrive each unit site, listen to each unit management radioisotopes and radiation related management report、inspection units archives、on-site inspection of protective equipment and use instruments to monitoring related data methods, census of all units, and analyze the collected and monitored data。All data were analyzed using EXCEL 2010 entry, statistical analysis was performed using SPSS 18.0。Results:1, As of September 2014, there are 216 regular health supervision in Suzhou City (There are 43 about ray apparatus for medical applications, Industrial-ray apparatus 137 units, radioactive sources apparatus 36 units), supervision and inspection pass rate of 96.76%。The rate of holds a valid 《Radiation Work Health Permit》 is 96.76% in Suzhou City work unit of radiation; permittee rate-ray apparatus for medical application units (100%) higher than the rate of industrial radiography devices permit the use of units and sources (respectively 97.81% and 94.44%), but there was no significant difference between groups (P>0.05)。Explain the regulatory department to medical radiation devices、ray equipment for industrial applications and radioactive sources units are carried out strict management, There is a strong sense of self-management units most radiation work。In addition,《Radiation Work Health Permit》 valid permit rate (96.76%) less than 《Radiation Staff card》 valid permit rate (98.25%), and two card holders rates differ statistically (P<0.05)。2, In external radiation levels,the ray apparatus for medical monitoring point with a pass rate is 99.53%, ray apparatus for industrial monitoring point with a pass rate is 99.59%, Radioactive Sources monitoring point pass rate is 98.20%。Monitoring of external radiation levels in each group qualified was no significant difference (P> 0.05)。3, The different types of radiation staff training rate has statistical significance (P <0.05), It can be seen, Different radiation device uses unit staff training situation is different, Some units is not enough emphasis on staff training of the radiation, in future work, to strengthen supervision and inspection in this regard, strive to make each unit of employee training rate in subsequent checks are able to meet the requirements。4, Among different types of radiation workers participate in healthy check has statistically significant (P<0.05)。It can be seen, Each unit not regularly organize all employees to participate in healthy check。5, Outside dose should be monitored to check 456 people in Suzhou City, however, the actual monitoring inspection 452, the rate of monitoring is 99.12%。For all radiation workers per capita effective dose values not exceed the limit (scilicet 20mSv), and the vast majority (98.00%) the per capita effective radiation dose values annual staff within the limits of 1/10 (cilicet 2mSv), is a low-dose occupational exposure category, This is the work over the years continued to strengthen radiation protection、strengthening the related staff radiation protection training and education knowledge、the stringent requirements to proper use of ray device、radioactive Sources and radiation protection equipment and other measures played a key role。Conclusion::1、there are 216 regular health supervision in Suzhou City, 《Radiation Work Health Permit》 valid permit rate (96.76%) less than 《Radiation Staff card》 valid permit rate (98.25%), and two card holders rates differ statistically (P<0.05)。2、In external radiation levels,the ray apparatus for medical monitoring point with a pass rate is 99.53%, ray apparatus for industrial monitoring point with a pass rate is 99.59%, Radioactive Sources monitoring point pass rate is 98.20%。Monitoring of external radiation levels in each group qualified was no significant difference (P> 0.05)。3、The different types of radiation staff training rate has statistical significance (P <0.05)。4、Among different types of radiation workers participate in healthy check has statistically significant (P<0.05)。...
