IndustriesRegulatory bodies demand for

unified opinion

How can we get unified public opinions?

• Varieties of interest situations– Observing bands

• HF ↔ sub-mm– Telescope diameter

• Small 1m ↔ large 64 m– Location

• cities ↔ mountains– Run by

• University laboratory ↔ NAOJ

• Sometimes, there might be conflicts of interests.

Thus we need a committee to discuss.

• This is “Radio Astronomy Frequency Committee in Japan ”.

Structure to Accomplish the Committee’s Role

• NAOJ is the only one observatory for common use in Japan.

• It is supported by Japanese astronomers’ community.

• Thus, it is appropriate to have a division to handle regulatory matters.

The Secretary Division of the committee

• We have secretary division of:– 1 full-time personnel– 2 part-time personnel

• Costs are paid by NAOJ.• Backgrounds:– Committees are volunteer-based generally.– Committee members meet and discuss, but are not

expected to work. – But we have to work every day to protect radio

astronomy against industries.– The solution is to have a secretary division.

Summary

• We have to have a national body for each country or region to decide and propose better regulatory ways to the regulatory authorities for radio astronomers.
