管理システムを構築することが可能となる。Conventionally, when entering a radiation controlled area, the contamination status of the individual was checked using a hand-foot cloth monitor when entering or exiting the area, and if there was contamination, the contamination was removed and measured again using this monitor, and the result was determined to be OK. People were entering or leaving the premises. This hand foot cloth monitor is shown on the left side of Figure 2, for example, and is published by Maruzen KK on 859-12-20.
It is listed on page 526 of the "Isotope Handbook" (revised 3rd edition), and the contamination status of left and right limbs and clothing is checked. The hand foot cross monitor m shown in the figure performs measurements at that time, but normally does not record the measurement results. However, when a radiation worker performs work, it is difficult to manage whether the worker leaves without contamination or whether the worker leaves as a result of decontamination due to contamination, for example. Unfortunately, if you are the only one who is contaminated while other workers are not, you will need to instruct that worker on how to do the work, and if more than one person is contaminated, the entire work itself will need to be taught. If there is more contamination than expected even though the work was carried out in a normal manner, check to see if there is a leak of radioactivity within the facility. be able to. If measurement results can be managed in this way, it will be possible to construct a better radiation management system.

。Even if there is a case where the measurement results are recorded in a memo, etc., each person must take notes, and there may be cases where the user does not take notes or do not write accurate values. We took this as an example, but the same problem may occur when using other radiation measuring instruments.

This result is shown in Fig. 4. For example, if the first measurement value S of the left hand is 150 cpm, it is at an acceptable level (for example, 80 cpm).
