[ RadSafe ] Oncology 'laser', questions

Fri Nov 24 00:57:00 CST 2006

Laser is in quotes because it is being used lightly. In reality it is a light 'pen', designed for near contact application of source light to tumor surface. As for the light being emitted, here is an excerpt from Wikipedia:

"Radon

Notable characteristics

Essentially chemically inert, but radioactive, radon is the heaviest noble gas and one of the heaviest gases at room temperature. (The heaviest known gas is Uranium hexafluoride, UF6.) At standard temperature and pressure radon is a colorless gas but when it is cooled below its freezing point it has a brilliant phosphorescence which turns yellow as the temperature is lowered and orange-red at the temperature air liquefies."

My guess is the light is always there but only visible to the naked eye when it is cooled enough to slow the resulting photons to the visible light band?

Let's not go 'poo pooing' a theory which is in its infancy. I'm looking for feedback and collaboration here. This is one of the purposes of this list. There are a lot of you out there with a lot on the ball. If this idea has a potential for benefit to cancer sufferers, it is in everyone's interest to iron out the kinks and get on with it.

RADSAFErs,

It took a long time at RADSAFE to clarify the difference between Ra and Rn,

to clarify that Ra-226 decays to Rn-222 and that this will not build up to

infinite pressure but to the equilibrium according to its short half-life. I

can confirm the contribution of Wes by facts: It is known, that explosions

of glass contained radium sources occurred partly due to He-build-up. Some

explosions were attributed to formation of hydrogen and oxygen due to

radiolysis of crystal water, but I am very sceptic about that - chemists (I

am one) dry their salts extremely carefully because of yield determination

and anyway how should this gas mixture have been ignited? I know for

sure,that flame-sealed glass containers with sources of radium (in the

Ci-range) were carefully opened at the former Institute of Radium Research

to release the pressure of He-gas formed in the meantime.  

But much more than these topics I am bothered by other questions. 

Can somebody tell me why light is emitted by simply cooling down a gas?

Never heard about this, but would appriciate any information to improve my

knowledge. Secondly I would like to know, how light emitted by any process

would - obviously without any intermediate treatment! - be suddenly

transformed into a laser? I am a laser-layman, so please "enlighten" me.  

Best regards,

Franz
