Variation of radon progeny concentration over a continental location
Background: The variation of the radon progeny concentration in outdoor environment and meteorological parameters at fine resolution were studied for one year at a continental location, National Atmospheric Research Laboratory, Gadanki, India. Materials and Methods: The concentrations were measured using Alpha Progeny Meter by collecting air samples at a height of 1 m above the Earth&rsqu...

متن کاملIntegrating Radon Progeny Monitor
INTRODUCTION The Japan Nuclear Cycle Development Institute (JNC) carried out research and development projects related to uranium exploration in Japan from 1967 to 1987. Several mining facilities have been retained after the end of projects. Hence, the study on the behavior and the environmental impact of radon and its progeny from the mining facilities is being continued at the Ningyo-toge Env...
متن کاملDiurnal variation of radon progeny.
The diurnal variation of the gross alpha (alpha) radioactivity in the air near the ground and the gamma (gamma) radioactivity emitted from the ground have been monitored in North-eastern Greece. Meteorological information comprising air temperature and humidity has been simultaneously recorded. Over a period of the 24h of a typical day, the variation of alpha-radioactivity reaches a peak in the...
متن کاملBronchial dosimeter for radon progeny.
A true bronchial dosimeter has been designed, consisting of four 400-mesh wire screens and a filter paper. With a face velocity of 3.3 cm s(-1) for home exposure and 4.6 cm s(-1) for mine exposure, the deposition pattern on the wire screens were found to satisfactorily match the variation of the dose conversion factor (in units of mSv WL M(-1)) with the size of radon progeny from 1 to 1000 nm. ...
