BACKGROUND
At the Council meeting of Se~tember 21, 2009, correspondence from Goldak Airborne Surveys
was referred to staff for further information.
Goldak has advised that they. have been contracted by Health Canada to perform a regional
survey as part of a national program to measure natural radiation which occurs from
potassium, uranium and thorium, and to produce maps of an entire area. Health Canada is
finding areas that may be of c¢oncern for radon contamination. In areas where a concern is
found, it may be necessary fdr the Building Code to be amended to ensure proper protection in
basements as radon is heavier than air. Through this survey, Health Canada will be
establishing baselines.
A survey of the London area was completed last year. The survey is undertaken by flying a
twin-engined Pipe Navajo aircraft equipped with survey equipment and two pilots at an altitude
of 150 metres above the highest obstruction in the community. They will be flying a grid
pattern with flight lines 1 kilometre apart so the number and frequency of passes and noise
impact to the community will be minimal. The survey will be conducted between September 1
and December 1, 2009.
The correspondence was sent to the Municipality as part of the submission of their "Work Zone
Plan" to Transport Canada requires them to advise the Municipality of their work and to receive
confirmation that we have received notification. This confirmation has been forwarded to
Goldak Airborne Surveys.
A map of the survey area is attached.
This report is provided for Committee's information.
