Summary

At use of track detectors TDA-01 and Petryanov's fibre filters in 2000 - 2010 were measured con-centrations of radon and its daughter products (DP) in rooms of "Ukryttya" object. Was established that ac-tive median aerodynamic diameter of aerosol-carrires of DP have diapason 0.08 - 0.8 mkm. The radon moni-toring in 2006 - 2010 in rooms of "Ukryttya" object showed that average annual radon concentration exceed 150 Bq/m3. The largest concentration 800 Bq/m3 was detected in room 012/7, were be found lava lace fuel-containing materials. At the middle radon concentrations 170 Bq/m3 and thoron concentrations 10 Bq/m3 supplementary inhalation radiation stand comparable to regulation standard. Presence of DP in rooms of "Ukryttya" object is the negative factor of radiation situation.
