  2. MOTIVATION ANNUAL RADON DOSE ASSESSMENTS (mSv) INDOOR RADON CONCENTRATION (Bqm-3) MODELS: - Epidemiological assessments (ICRP) - Physical dosimetry (UNSCEAR)

  3. RADON MEASUREMENTS • 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

  4. SHORT-TERM RADON MEASUREMENTS RESULTS: Indoor radon measurements performed in the August and September for the three days in the living room

  5. SHORT-TERM RADON MEASUREMENTS RESULTS: Indoor radon measurements performed in the August and September for the three days in the bedroom

  6. SHORT-TERM RADON MEASUREMENTS RESULTS:

  7. 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 nottrivial and mostly influenced by the radon variability.
