项目摘要

1. For the purpose of educational use of environmental ionizing radiations. we have made a simple gamma-ray counter consisted of a portable survey meter and a pocket-computer. The interface circuit of survey meter and pocket-computer was handmade. The relative intensities of environmental gamma-rays were measured along the road in Fukui. The intensities increased, when passing through tunnels or by cliffs, and the geological effects were observed at Wakasa district. We can use this system as a teaching material of computer-assisted measurement.2. The measurement system which combined the pocket computer, the digital to analog conversion circuit, the comparator circuit and the counter circuit was established. The student experimented with this device They did the program making maneuver for the measurement and control, and they measured the energy spectrum of gamma rays by the window type pulse height analysis method. Their concerns for the ionizing radiation can be deepened, studying the electronic circuits and the computer3. We made another apparatus to measre the equvalent dose rate of environmental gamma-rays and to collect the landscape-image of survey route. This consists of a gamma-ray survey meter, AD converter, a note personal-computer, and a digital video camera. We take a picture of the landscape of the survey route, measuring the equivalent dose rate of environmental radiation. The note personal-computer accumulates the data of equivalent dose rate. The data in note personal-computer and the image of survey-route are moved to a personal-computer and are synthesized. As a result, we intuitively understand the relation between the backgroud radiation and the environment. This is effective to the basic education of ionizing radiation.

1.用于环境电离辐射的教育用途。我们用便携式测量仪和袖珍计算机组成了一个简单的γ射线计数器。测量仪与袖珍计算机的接口电路是手工制作的。在福井县的道路沿线测量了环境γ射线的相对强度。在若狭地区，通过隧道或悬崖时，强度增加，并观察到地质效应。该系统可作为计算机辅助测量的教材.建立了由袖珍计算机、数模转换电路、比较电路和计数电路组成的测量系统。学生们对该装置进行了实验，编写了测量和控制的程序，并用窗口式脉冲高度分析法测量了γ射线的能谱。他们对电离辐射的关注可以加深，研究电子电路和计算机3。我们研制了另一套测量环境γ射线当量剂量率和采集测量路线影像的装置。该系统由伽马测量仪、AD转换器、笔记本电脑和数码摄像机组成。我们拍摄调查路线的景观照片，测量环境辐射的等效剂量率。笔记本电脑积累等效剂量率的数据。将笔记本电脑中的数据和测量路线的图像移到一台电脑上进行合成。从而直观地了解了背景辐射与环境的关系。这对电离辐射基础教育是有效的。
