30年前，随着贝塔二级标准(BSS)的制定，为将贝塔辐射吸收剂量率的单位传播到组织中奠定了重要的基础，这在实践中证明了其价值。BSS广受欢迎的主要原因是其校准可追溯到PTB的基本标准量度装置，以及它符合国际标准ISO 6980的建议。1996年，开始对BSS进行广泛的改装，目的是改善其操作简便性，实现更多的实际使用，确保进行辐射时的质量，并优化辐射防护。在接下来的报告中，将介绍这一优化的结果，新的Beta二级标准类型2(BSS 2)。为此，我们将报告对BSS 2进行的调查，以及在BSS 2的工作中获得的经验，以及迄今对32套辐射源进行的校准。
With the Beta Secondary Standard (BSS), an important basis was created thirty years ago for the dissemination of the unit of the absorbed dose rate of beta radiation to tissue, which has proven its worth in practice. The main reasons for the popularity of the BSS are the traceability of its calibration to the primary standard measuring device of PTB and its conformity with the recommendations of the international standard ISO 6980. In 1996, an extensive modification of the BSS was started with the aim of improving its ease of operation, achieving a greater variety in practical use, assuring the quality when performing irradiations and optimizing radiation protection. In the following report, the result of this optimization, the new Beta Secondary Standard type 2 (BSS 2), will be presented. To this end, we will report on the investigations carried out on the BSS 2 and on the experiences gained in the work with of the BSS 2 and the calibration of - so far - 32 sets of radiation sources.
