[en] We investigate the new type dosimeter to prepare for renewal of the present TLD in the near future. We hope the new dosimeter to be able to adopt to a radiation working environment in the ODC's radiation control area and be more useful to carry out the personal exposure monitoring. The objects of investigation are TLD, OSL dosimeter, Glass dosimeter, Electric pocket dosimeter and Solid state track detector. And this report have made using technical data presented by each maker. As a result of investigation, we recognize that The TLD's performance is so good that we can continue to use for personal exposure monitoring even if it is compared with other recently new type dosimeter. If we pursue the rationalization and convenience in the operation of dosimeter more and more, then we will recommend the electric pocket dosimeter positively. We recognize obviously that the electric pocket dosimeter can provide us available function and good artificial operation. (author)
