Sine wave inverters with more than three steps in the wave output are more complex and have significantly higher cost than a modified sine wave, with only three steps, or square wave (one step) types of the same power handling.
A healthy cell has a pH of 7.35 while a cancer cell is more acidic. Cesium when taken orally will raise the pH of cancer cells, but not that of normal cells. When the pH of a cancer cell goes above 7.5 it dies and if it goes above 8.0 it will die in a matter of hours.
When they are taken up by the cancer cells, they will thus raise the pH of the cancer cells. Since they are very alkaline as compared to the weak lactic acid, it is possible that the pH will be raised to values in the 8.0 to 9.0 pH range.
