our Radon-Meter TMT-RD-35 you can determine the
concentration of radon in your house. As radon concentrations
vary greatly, the device has the possibility of short-term
and long-term measurements. The short-term measurement
can be set from 1 to 7 days and the measured
value is updated every 30 minutes. The average values for the
last 365 days are displayed in long-term
mode. This value is updated every 24 hours. Dangerous
high concentrations are indicated by an optical warning.
These measurements help to detect dangers arising from too high
radon concentrations and to avoid them by taking suitable countermeasures.
With the included USB charging cable, you can easily charge the
battery at any USB port.
Radon is considered besides smoking to be one of the most common
cause of lung cancer. Radon is a radioactive pollutant
that occurs as a natural gas and escapes from soils and building
materials. Via the cellar walls and basement, radon penetrates
into the interior of houses, where it can accumulate considerably
due to poor ventilation. The gas is invisible, it does not smell
and taste and penetrates the house in the basement without any
warning. The average radon concentration in Europe is about 50
Bq/m³. 100 Bq/m³ should not be exceeded in the annual
simple measures such as daily airing or permanent
ventilation with open windows on the windward side are enough.
In the house an overpressure means, no further radon is "sucked"
from the soil and existing Radon is "blown out" from
the house. It should also be kept in mind that any generation
of negative pressure in the house is to be avoided, e.g. Ventilators
for ventilation in the kitchen or bathroom or a lack of ventilation
in the heating system. All this leads to a vacuum in the house
and subsequently to the aspiration of radon from the ground. If
these simple measures can not lead to success, structural
measures such as sealing cracks in the cellar, ventilation
of outside air into the cellar, etc. can be taken. In the fewest
cases, complex restoration measures such as concreting,
foil sealing, drainage, etc. are necessary. However, the basic
prerequisite is always a reliable determination of the
measured value with our Radonmessgerät TMT-RD-35.
measurements can be used as a short-term measurement
to measure a room in which you stay most of the time like living,
sleeping and children's rooms (at least 5-7 days). However, the
most representative are long-term measurements in the cellar over
the entire year because Radon penetrates the cellar and only in
a long-term measurement the strong seasonal fluctuations can be
recorded. The longer a measurement is carried out at the desired
location, the more surely the radon concentration can be determined.
The lower the displayed measured radon value is after 2-3 days,
the longer the measurement should be carried out to obtain exact
results. For measurements below 50 Bq/m³, the measurement
should be continued for at least one week.
