In this year, twenty of the portable ELF magnetic field dosimeters have been designed and manufactured based on the design sheet developed last year. They satisfy the electrical performance required, and the final performance is as follows :(1) Size : 135mm x 90mm x 35mm (including the power supply)(2) Weight : about 250g including the power supply(3) Measured values : time-integrated values of three orthogonal components independently(4) Magnetic flux density : 0.02-550 micro tesla(5) Integrated values : 0.01-1999 micro tesla-hour(6) Time duration : 30 hours continuouslyA couple of on-site measurements using the present dosimeters reveal some mechanical defects of the dosimeter, and the dosimeters are still under construction. Consequently no systematic data on the dose characteristics expected are not yet obtained, and further investigation will be required.On the other hand, power frequency magnetic field survey has been conducted under 500kV over-head power transmission lines, in the 500kV power substation area and in the residential area, all in Indonesia as well as in Japan. Some valuable data on the elf magnetic field characteristics have been obtained from the present project. A part of the present survey was presented at "Seminar on Biological Effects of EMF in Indonesia" held at Bandung, Indonesia.

根据去年开发的设计图纸，本年度共设计制造了20台便携式极低频磁场剂量计。满足电性能要求，最终性能如下：(1)尺寸：135mm x 90mm x 35mm（含电源）(2)重量：含电源约250g(3)实测值：三个正交分量独立时间积分值(4)磁通密度：0.02-550微特斯拉(5)积分值：0.01-1999微特斯拉-小时(6)持续时间：使用现有的剂量计进行了几次现场测量，发现该剂量计存在一些机械缺陷，而且该剂量计仍在建造中。因此，尚未获得有关预期剂量特性的系统数据，需要进一步调查。另一方面，在印度尼西亚和日本的500kV架空输电线路下、500kV变电站区域和居民区进行了工频磁场调查。本工程获得了一些有关极低频磁场特性的有价值的数据。本调查的一部分已在印度尼西亚万隆举行的“印度尼西亚电磁场生物效应研讨会”上提出。
