Regimul aeroionizării naturale, evaluat pe baza meto<strong>de</strong>i clasice cu ajutorul unui contor <strong>de</strong> tip<br />
Ebert, indică <strong>de</strong>osebiri între cele două saline. Astfel, concentraţiile <strong>de</strong> ioni <strong>de</strong> ambele polarităţi (numărul<br />
total mediu <strong>de</strong> ioni din unitatea <strong>de</strong> volum) corespunzătoare perioa<strong>de</strong>lor <strong>de</strong> măsurare a fost <strong>de</strong> circa 710<br />
ioni /cm 3 (370 ioni pozitivi/cm 3 , respectiv 340 ioni negativi/cm 3 ). De semnalat faptul că, <strong>de</strong>osebirile<br />
cantitative dintre cele doua polaritati nu sunt mari, coeficientul <strong>de</strong> unipolaritate fiind foarte aproape <strong>de</strong><br />
unitate.<br />
Distribuţia cantitativa totală şi pentru cele două polarităţi (ionizare pozitivă şi negativă) este<br />
apreciată ca apropiată <strong>de</strong> valorile întâlnite în atmosfera liberă (din zone fără poluare) la salina Ocna Dej,<br />
aspect pozitiv prin efectele favorabile exercitate asupra organismului uman.<br />
MICROCLIMATE AND AIR IONIZATION MEASUREMENTS IN THE OCNA DEJ<br />
SALT MINE<br />
Ambient air is characterized by several physical parameters, such as the meteorological, but also<br />
by some electrical properties (air ionization). All these parameters influence on human organism and,<br />
therefore, they can be harnessed for therapeutic purposes, both in normal environmental conditions, and<br />
in special locations such as salt mines.<br />
The microclimate and natural ionization of air <strong>de</strong>terminations, performed at the Ocna Dej salt<br />
mine <strong>de</strong>ca<strong>de</strong>s ago, supplemented by new observations were ma<strong>de</strong> in summer 2009 in or<strong>de</strong>r to capitalize<br />
speleoterapeutice purposes of internal spaces.<br />
From the microclimatic point of view, in summer time, the un<strong>de</strong>rground areas have a mo<strong>de</strong>rate<br />
regime in terms of key meteorological parameters of the system. This thermic regime is relatively cool<br />
(with air temperatures ranging from 12,4 to 13,8 0 C), with a relative humidity of the air in a relatively<br />
close (56 - 65%) and almost non-existent air currents. Exceptions are the moments in which operate the<br />
aeration system and the observation points located in narrow portions of the mine, such as crossing lanes.<br />
Throughout the whole period of measurement was found stable microclimatic characteristics, due<br />
to very small changes in both the day to day and between measurement points. You could say that, in<br />
general, measurements have revealed a constant microclimate, cooler, which helps the stimulation of the<br />
body.<br />
The bioclimate expressed by the body’s thermal comfort in<strong>de</strong>x was bellow the comfort zone,<br />
specifically in the area of discomfort by cooling at all points of observation (5 – 14 0 TEE). In the sport<br />
hall temperatures were low, the lack of air flow and low relative humidity cooling caused a mo<strong>de</strong>rate<br />
discomfort. The stress skin was hypotonic (specifically winter months) in all observation points, but only<br />
un<strong>de</strong>r “gym” in the sanatorium was slightly hypotonic for relaxing.<br />
Stress lung, calculated from water vapor tension, shows a character <strong>de</strong>hydrated (specific winter<br />
months) at all points and slightly <strong>de</strong>hydrated in the gym and at the entrance of the Sanatorium Hall<br />
(corridors intersection).<br />
The natural air ionization regime, assessed using conventional classical method based on an<br />
Ebert-type meter, indicates the differences between the two salt mines. Thus, both polar ion<br />
concentrations (average total number of ions per unit volume) corresponding to periods of measurement<br />
was about 710 total ions/cm 3 (370 pozitive ions/cm 3 , respectively 340 negative ions/cm 3 ). It pointed out<br />
that the quantitative differences between the two polarities are not large, the coefficient of unipolarity is<br />
very close to unity.<br />
The total quantity and distribution for the two polarities (positive and negative ionization) is<br />
appreciated as close to the values found in the free atmosphere (in areas without pollution) at the Ocna<br />
Dej salt mine, an positive aspect due to the favorable effects exerted on human body.<br />
