Title: Personal alarm dosimeter and environmental dosimeter
Inventor: YAMAMURA KIYOHITO
IPC: G01T1/02
Filed: 1998-03-31
Abstract: PROBLEM TO BE SOLVED: To accurately measure radiation dose other than γ rays by calculating the amount of compensation for compensating for the detection amount of the γ rays of a detector other than the γ rays based on the count value of a γ-ray detector, and by integrating the difference between the count value and the amount of compensation. SOLUTION: The exposure dose of γ rays is calculated according to an integration count value up to the end of work. On the other hand, the exposure dose of β rays is calculated according to β- and γ-ray trend count values from the start to end of the work. Time from the start to end of the work is divided by the interval of five minutes. The amount of γ-ray compensation for each division time interval is calculated according to γ-ray count value for each division time interval, namely the γ-ray trend count value. On the other hand, the amount of γ-ray compensation is subtracted from β-ray count value for each division time interval, namely the β-ray trend count value, and the count value corresponding to the amount of the β rays for each division time interval is calculated.  Only positive count values corresponding to the amount of the β rays for each division time interval are integrated over working time, and the integration value is set to the counter value corresponding to the amount of the βrays at the working time, thus the exposure dose of the β rays can be calculated.
