Investigation On Radioactive Level Of The Rural Hospitals In Xinjiang

Objective:To learn about the radiactive level of the rural hospitals in Xinjiang;To explore the main factor of the radiactive level of the rural hospitals, to provide new ideas of the protection for rural hospitals, to provide reference for the health isnpection.Methods:To monitor the radiation level around the rural hospitals using, 451P-DE-SI,6134/H,6150AD/bχandγRadiation Doserate Meter.To measure the individual dose of external radiation upon the radiation work staff by LiF(Mg,Cu,P) powder, through thermoluminescence detection usingTOLEOO-654 England thermo luminescence reader, BR-2000 thermo luminescence annealing furnace. To evaluate the radiation dose level around the rural hospitals as per the national standard and analyze the key points of health safe. Full blood Samples were cultured and aberrative cells were analyzed with microscope.Results:The Medical X-ray machines accounting for 53.2% in the rural hospitals,50% rural hospitals for the year 2000 configuration equipment purchase, but for domestic equipment, The fluoroscopic equipment,75% of the equipment useful wire measured values>2.5 cGy/min,56.2% equipment made a protective area between 41-50uGy.47 of radiological worker's chromosome aberrtion rate and micronucleus rate were in the normal range. but no significant differences existed (p>0.05)with the those served shorter. WBC and PLT abnormal rate is 12.8% and 6.4%, in the average level of the reports. The abnormal rate of WBC and PLT is no significant difference (P>0.05) with the different length of service. Only 44.7% radiological workers wear TLD, the average dose equialent:1.85 mSv/a.Conclusion:The equipment of rural hospitals in Xinjiang is poor. The radiation level around the rural hospitals is higher. The dose equivalent level is higher than the same average dose radiation workers. There is no significant differences existed (p>0.05) (the chromosome aberration, the micro-nuleated cell, WBC, PLT) with the those served shorter. We should pay attention to the long-term low-dose radiation exposure. The TLD using is lower. The radiation occupational health surveillance and occupational health services should be increased.
