Electrode Shape: Which One to Choose?
1) How long do the electrodes last?
The electrodes will be good until they break or crack. Sometimes if knocked multiple times, the glass may develop a micro-crack and the gas will escape. As a result, the electrode will stop working.
If the electrodes were sitting without use for a long time, the gas may shrink (it can also happen if the electrodes are subjected to low temperatures). In this case, it may take some time to ignite the electrodes when first used.
Other than that, the electrodes may serve you for many years.
2) Can the electrode be used on the Neck?
There is a Y-shaped electrode that was initially designed to be used on the neck. Make no mistake! It was designed to be used on the back of the neck for relaxation.
Never apply an electrical current to the throat, where the thyroid gland is located. The application is limited on under the chin area and alongside neck muscles (sternocleidomastoid).
3) My electrodes do not glow
Pure Argon electrode glows pale lavender. If you start it in the brightly lit up room, you may not see the color: it will produce the familiar crackling sound and ozone odor, but appear not glowing.
Test the same electrode in the dark room to make sure it works.
Here is a video that demonstrates the testing and application techniques for Argon electrodes:
4) Does the electrode produces ionizing radiation?
Ionizing radiation consists of Gamma rays, X-rays, and the higher ultraviolet part of the electromagnetic spectrum devices. Ionizing radiation is invisible and not directly detectable by human senses, so radiation detection instruments such as Geiger counters are required to detect it.
The High-Frequency device emits static electricity only and does not produce any of the above. It has been on the market since the 1900's, so any concern of this nature would be very well documented.
