Evaluating The Experience Obtained From The Measurement Of Light Air Ions In A Cave

Light negative air ions demonstrably exhibit positive influence on the human organism. In the cave is extreme difficult measure air ions concentration because the climate in the cave is very wet. During the measure the average humidity was 100% and temperature was 7.2 degrees C. In the cave was performed measurement with ground Gerdien tube and measurement without ground Gerdien tube The concentration of these ions can be effectively used as the integral criterion for the evaluation of air purity, and there also exists a multitude of other applications. In a gerdien tube fitted with a one-piece inner electrode, measurement of the saturation characteristics must be performed to facilitate the determination of the air ion mobility spectrum. To measure the air ion concentration in cave, we designed a device utilizing a Gerdien tube; the apparatus facilitates long-term measurement in difficult climates, especially at high humidity, which is an option not available in standard experimental or commercial ionmeters. The results obtained from such measurement thus embody a unique complement to the previously published findings concerning the environment in the individual sections of cave. The investigation within the present paper focuses on the effects exerted by the cave walls, temperature, and air flow on both the concentration of air ions and the restoration of the environment following the patients' presence in the cave.
