MOTIVATION
INDOOR RADON CONCENTRATION
(Bqm-3)
ANNUAL RADON DOSE ASSESSMENTS
(mSv)
MODELS:
- Epidemiological assessments (ICRP)
- Physical dosimetry (UNSCEAR)
Short-term measurements:
- This type of measurements are performed with much more complex and expensive passive or active (pump air sampling) continuous measuring devices.
- Temporal distribution
Long-term measurements:
- Passive integrated measuring devices based on the nuclear track detectors, which is due to their low cost, simplicity and characteristics have ability to collect information from a large number of the measurement points at the same time.
- Spatial distribution
RADON MEASUREMENTS
SHORT-TERM RADON MEASUREMENTS
RESULTS:
Indoor radon measurements performed in the August and September for the three days in the living room
SHORT-TERM RADON MEASUREMENTS
RESULTS:
Indoor radon measurements performed in the August and September for the three days in the bedroom
Month
Living roomMean/Averaged from 16 to 24 hours
BedroomMean/Averaged from 24 to 08 hours

SHORT-TERM RADON MEASUREMENTS
RESULTS:
CONCLUSIONS
-The results presented in this work show that it is difficult to estimate the annual radon concentration due to the very complex indoor radon behavior. This task is not trivial and mostly influenced by the radon variability.
