ALARA概念的评价方法之一是通过明确对比各种剂量的结果来确定是否存在显著性差异。利用剂量监测数据作为一种指标,即可评价剂量及用以确定显著不同之点。对这些异常的位点作进一步的评价,决定程序是否需要改进,以便降低ALARA的照射。作者利用四种放射照相操作的年剂量测量结果考察了这种对比的评价方法,应用程序确定这些剂量监测数据在统计学上是否存在显著性差异。方法学:由四种不同设计方案中获得放射照相的个人年剂量记录的结果。在评价期间,所有四种方案都只使用~(192)Ir源。用统计分析系统(SAS)一般线性模型程序(Go79)的方差分析评价了这些数据。
One way to evaluate the concept of ALARA is to determine if there are any significant differences by clearly comparing the results of the various doses. Using dose monitoring data as an indicator, the dose can be evaluated and used to identify significant differences. These abnormal sites for further evaluation to determine whether the program needs improvement in order to reduce the exposure of ALARA. The authors examined the method of evaluation for this comparison using four dosimetric measurements of radiographic operations and the application determines if there is a statistically significant difference in these dosimetry data. Methodology: The results of individual annual dose records of radiographs obtained from four different designs. During the evaluation, all four schemes used only ~ (192) Ir sources. The data were evaluated using analysis of variance (ANOVA) with the General Linear Model of Statistical Analysis System (SAS) program (Go79).
