<p>A radiation detector for detecting a radioactive substance having been accumulated in a tissue in vivo after administering a radioactive drug, whereby the radioactive substance can be adequately detected depending on the type of a patient, etc. This radiation detector has a plural number of algorithms for ranking the detected radiation dose and these algorithms can be switched depending on the type of a patient, etc. Further, the radiation detector is provided with a display 18 (for example, an LED). Based on signals generated from the display, an operator of the detector can recognize how the detected radiation dose is ranked.</p> |
