[ RadSafe ] Chino Airport to clean radium contamination

[John R Johnson]

Susan and other radsafers

My experience with radium dials is that the radium stays on the dials. I
therefore assume that the contamination is radon progeny and need see if
that is stated in the bulliten.

Has anyone reviewed it?

Chino Airport to clean radium contamination

Tuesday, April 12, 2005 - CHINO -- One man's hobby to collect vintage
airplanes will cost San Bernardino County nearly $200,000 to clean up
radioactive material - at least temporarily.

The county will seek reimbursement after cleaning up the radium-226
contamination at Chino Airport, where Jeff Pearson, owner of
Preservation Aviation, Inc., stores vintage airplanes containing the
material. The radioactive material was used on the predominantly
American military aircraft to illuminate instrument dials. The aircrafts
date mostly from World War II through the 1960s.

"In both hangars, there is a quantity of old aviation instruments that
have the radium painted on the dial," San Bernardino County Director of
Airports Bill Ingraham said Monday.

The U.S. Environmental Protection Agency determined the radioactive
materials exceed the radiation limit and closed off the area March 10,
deeming it unsafe for entry, Ingraham said.

Twelve tenants of nearby hangars are still not allowed into the building
and cannot access their aircraft, airport Manager James Jenkins said
Tuesday. Their aircraft is not contaminated, but the area is, he said.

The county hired New World Environmental Inc. for $110,597 to clean up
the site and will pay an additional $85,000 to dispose of the
radioactive material in certified landfills. The Board of Supervisors on
Tuesday approved the funding, which comes from the Airports Capital
Improvement Fund.

"Since the county is owner of one building, and we own the land for the
other building, we are ultimately responsible," Ingraham said.

The county intends to recover the cleanup cost from the tenant, Ingraham
said.

The EPA's investigation of the Chino hangar stemmed from an
investigation into a warehouse in North Hollywood where the same company
was ordered to cease operations because of radioactive contamination
from the same source.

The FBI served the search warrant to investigate the hangars on behalf
of the EPA. New World Environmental Inc. is expected to start cleanup today.

EPA Onscene Coordinator Robert Wise said he could not comment on the
contamination as it was an ongoing investigation.

Pearson could not be reached for comment.
