[ RadSafe ] Oncology 'laser'

[Flanigan, Floyd]

Yes. .0001ml/day is rate for 1gram of Radium.

Floyd

Some clarification is required. The amount of Rn-222 given off depends
on
the amount of Ra-226 present and the amount of Rn-222 that builds up in
the
chamber reaches a maximum that is governed by its ~3.8 day halflife.

Radium 226 gives off Radon at a constant of .0001ml/day. This would be
in a sealed chamber with a mirrored interior surface and a fiber-optic
cable affixed to the only opening. The entire chamber would be cooled to
-195C and the Radon 222 emitted from the Radium 226 in the chamber would
be the source. The longer the Radium remained sealed in the chamber, the
more Radon would build up in the chamber, and, theoretically, the
stronger the source light would become. There would have to be a
throttle of sorts, controlling aperture size on the laser pen to control
the beam.

Do you mean Radium-226 or Radon-222?

Okay ... Here's the rub:



When Radon 226 is cooled to -195C, it gives off an orange-red light. If
said light was captured and channeled through a fiber-optic cable to a
light pen, and one incised a patient to expose a cancerous tumor, could
one affect said tumor with a Beta burn with the emissions from the light
'laser' pen? And if so, would this be an effective means of eradicating
said tumor?



How's that for a 'what if' ?
