CKML

CKML was a 50-watt radio station owned by Atomic Energy of Canada Limited through licensee "The Security Systems Coordinator, Chalk River Laboratories" which operated at 530 kHz on the AM band in Chalk River, Ontario, Canada.

The station was designed solely to broadcast emergency information in event of an accident at the laboratory.

The station was approved by the Canadian Radio-television and Telecommunications Commission (CRTC) in 1998.

The service was tested for one hour each month and, once a year, a two-hour emergency exercise was carried out.

According to the June 2020 issue of the Canadian Radio News Facebook page, CKML is off the air.
