Medical radiation on the 70cm band
----------------------------------
A radio-wave cancer therapy may be the latest in a string of devices to
share the 70cm band and join door openers, remote weather stations, wireless
headphones, alarms and a gaggle of other LIPDs.
In Melbourne a leading foxhunter Mark Harrison VK3BYY has tracked down a
signal that was triggering his club's UHF repeater.
He was warmly welcomed after entering a Collins Street Melbourne premises
and shown radio-wave equipment operating on 433-434MHZ.
It was explained to him that a cancer patient receives an injection of a
substance that acts on cancer cells. The theory is that the UHF radiation
blocks sugars reaching the cells to enable the therapy to be effective.
The patient has a folded dipole antenna placed near their body for several
hours a day for three weeks. The radiation seems to be a narrow band
frequency modulated signal with a tone.
A doctor told Mark VK3BYY that everything was approved for use, and then
adds that the radiation is 40 watts.
A member of the WIA/ACA Liaison Team has several discussions with the ACA
in Melbourne. The ACA understood that it was Low Interference Potential
Device, LIPD running milliwatts.
A solution is being sought, with talk of the device needing a shielded
enclosure to prevent it radiating on the 70cm band, that is a primary
allocation to Australian Defence and secondary for the Amateur Service.
There are reports that a dozen more similar radio-wave cancer treatments
units are planned for use throughout Australia.
