Analysis of the results of the nationwide interlaboratory comparison of gross α and gross β radioactivity measurement / 中国辐射卫生

Objective To summarize and improve the related technical issues by analyzing the nationwide interlaboratory comparison of gross α and gross β radioactivity measurement over the years. Methods According to the requirements of interlaboratory comparison and the national standards, the gross α and gross β radioactivity in water were measured, and the results were analyzed to identify the influencing factors. Results From 2018 to 2022, our laboratory participated in five nationwide interlaboratory comparisons of gross α and gross β radioactivity measurement. The Z-test values for gross α and gross β measurement ranged from −0.24 to 1.8 and −1.4 to 0.35, respectively. The relative deviations ranged from −4% to 32% and −18% to 6%, respectively. All comparisons were within the acceptable ranges. Conclusion The analysis of comparisons showed that the results were within the acceptable ranges. The relative deviations between the measurement and the reference values have decreased over the years. The summary and improvement of related technologies have improved the measurement accuracy.

Detection and analysis of iodine content of drinking water in Jingdezhen Municipality / 中国现代医生

Objective Iodine is a necessary microelement in human body. The major way for people to obtain iodine is drinking water. In this study, the drinking water is well water. We detected and analyzed the iodine content in drinking water. Methods The drinking water tested in Jingdezhen from March to October 2017 was selected, and 186 of these samples were used as the object of this study. All the objects were representative of the geographical conditions and population distribution of the city. Samples of drinking water were tested using the method recommended by the National Iodine Deficiency Disorders Laboratory of Chinese Center for Disease Control and Prevention (ie, spectrophotometry method with cerous sulfate). Results The iodine content ranged from 5-127. 66 μg/L, with 76 samples ＜10 μg/L accounting for 40. 86％, and 110 samples ≥ 10 μg/L accounting for 59. 14％. Conclusion The iodine content of drinking water in Jingdezhen can meet the needs of the human body. However, in some drinking water, the iodine content is relatively insufficient and it is necessary to use iodized salt to supplement the physical needs.

And we found 435 cases of suspected occupational disease which takes 5.05% of total number of review People, including suspected occupational noise deafness which takes the property of 60.23% and appears the most common disease. Suspected occupational diseases and occupational taboos are mainly male patients, and the age is mainly in the 30-49 age group, the working age is mainly less than 5 years. @*Conclusion@#Occupational health examination is an important Part in occupational health, occupational health examination review is the most Prior Part in the occupational health examination, which Plays a key role to discover the target disease of the occupational hazard factors in time, Prevent the development of occupational diseases and protect laborer occupational health.

Training and assessment of cardiopulmonary resuscitation skill among non-clinical medical staff / 实用医学杂志

Objective To explore better management of cardiopulmonary resuscitation(CPR)skill train-ing and assessment and to improve CPR skills of non-clinical medical staff. Methods We developed standard CPR process and produced operating video ,and CPR models were used to train and assess 385 non-clinical medi-cal staff then the results were analyzed. Results All the 385 non-clinical medical staff were qualified. The medi-an score was 86.0,and quartile spacing 9.5. Scoring rate and full mark rate were the lowest in assessing for breath-ing and pulse before and after rescue ,followed by chest compressions/rescue breathing and quality of CPR. Age had significant positive correlation with the score of step 12(assessing for breathing and pulse after rescue),(r=0.1,P < 0.05). Gender and different professional titles had no significant effect on the results of the assessment. Conclusions Non-clinical medical staff need to pay more attention to CPR skill. Sound system ,advanced and ef-fective training methods,repeated training and regular assessment are conducive to the improvement of CPR skill of young non-clinical medical staff.
