A surge of opposition to a proposed plant irradiation facility near Honolulu Airport is hardly unexpected. Opposition centers around fears that radioactive materials could be released through sabotage, accidents or even terrorism.

But the potential benefits of the plant are substantial for Hawai'i's growing agricultural economy. Decisions about whether to go ahead with this project should be based on sound scientific risk/benefit analysis and with consideration of the economic benefits it could bring.

Local environmentalists are asking for a formal hearing on the project before the Nuclear Regulatory Commission. They also are asking for either an environmental assessment or environmental impact statement.

Both requests are reasonable and, if granted, should go a long way to allay safety fears.

Hawai'i has one irradiation plant in operation today, on the Big Island. But that uses a different (X-ray) technology than the cobalt-60 technology proposed for the airport site.

The fact that the plant would use a different technology makes the call for environmental and safety review even more sensible.

If the plant is built, it will represent a big boon for local growers of tropical fruits and other exotics. The market for our high-quality produce is huge, but it is hampered by the necessity to get products treated for fruit flies and other pests.

Assuming that review concludes the plant will be as safe and effective as it is touted to be, it should move ahead.
