摘要： PROBLEM TO BE SOLVED: To reduce the influence of a background radiation caused by β-rays from an incident face of a photomultiplier. SOLUTION: A β-ray absorber 3 transparent sufficiently for a scintillation- emitted light wavelength and for absorbing the β-rays from the incident face 2 is arranged between a scintillator 4 and the incident face 2 of the photomultiplier 1, in a scintillation detector for amplifying fluorescence by a radiation in the scintillator 4 by the one or plural photomultiplier 1 to be detected.

摘要： PROBLEM TO BE SOLVED: To provide a radiation dose measuring method for predicting, calculating and displaying the final response value of a radiation dose measuring device, without having to wait for the lapse of time constant, and to provide a prediction-corresponding type radiation dose measuring device. SOLUTION: This radiation dose measuring device includes an output section for generating an output pulse due to incidence of radiation; a counting rate arithmetic section for counting arrivals of the output pulse and appropriately calculating the counting rate per second of count with a sampling time T; a moving average value arithmetic section for calculating the moving average value, based on a plurality of counting rates per second of the count; a prediction arithmetic section for predicting the counting rate per minute of the present count, based on the present moving average value, previous moving average value; and counting rate per minute of the previous count using the equation: N 0 =60×(M 0 -M -1 )/Δt+N -1 , and a display section for displaying the predicted and calculated counting rate per minute of the present count. Here, N 0 is the counting rate per minute of the present count, N -1 is the counting rate per minute of the previous count, M 0 is a present moving average value, M -1 is a previous moving average value, and Δt is sampling time.

摘要： PROBLEM TO BE SOLVED: To provide a detector which can measure the presence/absence of radioactive contamination without requiring frequent motion of eyes and without generating a click sound to acoustically inform a level of the contamination when the radioactive contamination is measured by a survey meter of a type with the detector and a measuring device separated and in which a visual display is turned on/off when a radiation measured value exceeds a control reference value. SOLUTION: In this survey meter of the type having the detector and the measuring device separated, the visual display means by one or a plurality of illuminants 3, 31 and 32 is set to a point such as a rear face of a hold part 2 of the detector, etc., where a measurer can visually recognize with ease. The illuminants 3, 31 and 32 are turned on or off synchronously with radiation pulses inputted to a scintillator part 1 of the detector.
