Hello cdmountainsr,
You asked 'What does this mean'...
Well I am not a doctor but as far as I am concerned the use of radiation on my body is totally and completely stupid to do. This is just my opinion. If you truly are desiring to restore your health, start a daily practice of Falun Dafa Qigong
This form of Qigong is easy to learn yet has the ability to completely restore you to radiant health rapidly - one to three months. The only thing that radiation does, again in my view, is take away from your health. And frankly there are many doctors out there that believe the same thing about it. Getting them to admit it is something else. To many constraints in the medical system.
The link above will take you to a website that provides free download videos of the 5 easy to learn exercises. The regular daily practice of these 'exercises' will in essence raise your body's frequency. Radiation does the opposite.
Here is a website that talks about the science of 'frequency' and healing... Love and Light... Gary
