[en] In the early years, the routine personal and environmental dosimetry at the health physics laboratory at the Nuclear Research Center- Negev was performed with badges using photographic films. In 1975, the TLD method was introduced. The routine personal dosimetry was performed by using the LiF:Mg, Ti phosphors (G-1 cards), measured by an automatic Harshaw 2271 reader. A manual 2000C system was also employed. The environmental measurements were performed by using the LiF:Mg, Ti cards or the sensitive CaF2:Dy ones. The heating of the phosphor was performed by a hot finger, and only whole glow curve integration could be used. From 1994, we are using a new automatic TLD reader (Harshaw/Bicron 6600) and a new manual TLD reader (4500) with new LiF:Mg, Ti cards; the chips are heated by a Nitrogen jet, and Computerized Glow Curve Deconvolution (CGCD) can be performed. In this presentation, the state of the art of the dosimetric measurements at the NRC-Negev is described. A quantitative comparison is made of some basic dosimetric properties obtained in the past and with the new system. It is evaluated that the standard deviation when employed the new system is improved by a factor of 2, and the MMD (Minimum Measurable Dose) is improved by a factor greater than 3. By employing the CGCD (which can be easily integrated in the new system), the fading of the main dosimeter peaks (4+5) is within the range of 8% for the period of at least one year, which is significantly less than the fading received when the whole glow curve is integrated for dose determination. The main features that contribute to the improvement achieved with the new system are mentioned. (author)
