<p><P>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. <P>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<SB>0</SB>=60×(M<SB>0</SB>-M<SB>-1</SB>)/Δt+N<SB>-1</SB>, and a display section for displaying the predicted and calculated counting rate per minute of the present count. Here, N<SB>0</SB>is the counting rate per minute of the present count, N<SB>-1</SB>is the counting rate per minute of the previous count, M<SB>0</SB>is a present moving average value, M<SB>-1</SB>is a previous moving average value, andΔt is sampling time. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
