RADON in a high karst area of Montenegro - A case study.

The national radon surveys in Montenegro revealed that the highest annual average radon concentrations (C) in ground floors of dwellings and schools were found in a rural region characterized as a typical high-karst area. In this region, spanning approximately 800 km, C values in 9 houses and 16 schools ranged from 219 to 2494 Bq/m, with AM = 977 Bq/m. To investigate the causes of these elevated indoor radon concentrations, the following parameters were measured near the 25 surveyed buildings: soil humidity, electrical conductivity, pH, activity concentrations of Ra, U, U, Th and K, radon concentration in soil gas (c), soil permeability for radon gas (k), and gamma dose rate in the air.

Cryopreservation of Indigenous Plums and Monitoring of Multiplication and Rooting Capacity of Shoots Obtained from Cryopreserved Specimens.

The objective of this study is to assess the suitability of vitrification cryo-plate (V cryo-plate) and dehydration cryo-plate (D cryo-plate) methods for the long-term conservation of eight autochthonous L. genotypes originating from the Balkan Peninsula region. In vitro shoot tips were briefly pre-cultured for 1 day at 23 °C in the dark on a medium containing 0.
