アンケート調査からみたICRP-60(1990年)勧告受入れに関する考察

抄録

The purpose of this study was to identify the reactions of hospitals to receiving ICRP-60 recommendations. The main questionnaire items pertained to changes in occupational exposure, antenatal exposure, and controlled areas. Of 255 facilities that received the questionnaire, 146 responded. Seventy-four percent of facilities received recommendations on occupational exposure and 63.7% on controlled areas. In terms of antenatal exposure, 73.3% of facilities received not ICRP-60 recommendations but the Japanese recommendations to enact regulations on period (week or month). The respondents considered (1) that recommendations on occupational exposure were unlikely to cause much confusion. However, 2.1% of facilities were engaged in improvements. (2) Respondents agreed that recommendations on antenatal exposure be enacted. In the absence of such regulation, alarm meters or pocket dosimeters should be used. (3) In terms of controlled areas, 26.7% of facilities considered that operation time must be examined.
