[The radon therapy: radon inhalation spa in Kowary].

In this paper the measurements of radon-222 concentration in the air of Kowary Radon Inhalatorium in the vicinity of Jelenia Góra, Lower Silesia, Poland, performed by Radiation Protection and Radiobiology Department of National Institute of Hygiene in Warsaw, have been presented. For the measurements the integration method with the application of charcoal canisters have been used. The radon concentration was found within the very broad ranges from about 4 to 420 kBq m-3 depending of the season of the year. Basing on the radon concentration measurements during the inhalation therapy session and taking into account the equilibrium factor of 0.8 the doses to the bronchi of the patients in range from 1.2 to about 204 mSv (0.12-20.4 rem) have been assessed. The majority of patients (ca. 76%) received the doses between 115 and 204 mSv.

[Exposure to radon-222 of inhabitants of buildings in Olsztyn].

The concentrations of radon-222 in the air of some buildings in Olsztyn were measured. The main source of radon in buildings is in general the ground under building and the materials used for building structure. In this work the results of radon-222 concentration measurements in the air of some buildings constructed before the 1939 year, in the buildings constructed after 1945 year with the traditional use of the bricks and in the buildings constructed with the use of great prefabricated plates are presented. The relations between radon-222 concentrations in the basements and in the first floor flats situated above the basement were evaluated. Based on the mean radon concentrations in the air of the various types of buildings investigated the effective doses for the inhabitants of each type of buildings were estimated.

[Measurements of radon 222Rn in water from the deep borehole in Warsaw].

Radon 222Rn in deep borehole water in the Warsaw's district has been quantitative determined. The measurements were performed using the alpha liquid scintillation counting method. The measurements results were compared to the 222Rn concentration limit in drinking water approved in other countries. In some cases the concentrations of 222Rn in investigated water samples exceed 11 Bq/l. The annual radiation dose equivalent received by the people consuming every day such water in Warsaw in about 0.014 mSv (1.4 mrem).

[Comparative analysis of two diffusion methods for radon Rn-222 estimation in atmospheric air by means of gamma ray spectrometry and liquid scintillation counting].

The comparative measurements of radon Rn-222 concentration in indoor air of some buildings and in radon labour chamber have been conducted using two different diffusions methods. The results of parallel measurements using radon charcoal detectors and gamma-rays spectrometry with liquid alpha scintillation counting (Pico-Rad) have been presented. It was concluded that both methods offer the similar measurements possibilities of radon concentrations in the air from about 30 Bq/m3 to about 600 Bq/m3 with the real average divergence between both methods of about +/- 11%.
