Scanning Mobility Particle Sizer Range 10 nm – 1 µm BACCHUS is a European FP7 collaborative project under the lead of ETH Zurich, Switzerland. In the next 4 years, 20 research institutions from the European Union, Switzerland, Norway and Israel work closely together in order to better understand key processes in aerosol-cloud interactions.

BACCHUS will generate a unique database linking long-term observations and field campaign data of aerosol, cloud condensation and ice nuclei and cloud microphysical properties; this will enable a better quantification of the natural aerosol concentrations and the anthropogenic aerosol effect.

Total and limited (0.25, 12.7 MeV) counts are shown

CONCLUSIONS Presented results confirm suitability of radiation environment at high altitude mountain observatories for long-term comparative measurements using devices intended for low-flux mixed radiation fields, namely such as that on board commercial aircraft. The experiments provided guidance for further development and improvements both of the calibration and data processing methodology. Agreement between data recorded by Liulin and AIRDOS devices both in-flight and during long- term measurement at the BEO Moussala is reasonable.

UV sensors UV sensor equipment and bio-container at Moussala BEO station. Experimental design

This pilot and unique experiment was conducted for 40 days to natural UV irradiation and gamma background at two altitudes in BEO station (Peak Moussala 2925 m asl) and the area of the Beli dam (1500 m asl). The selection of altitudes is consistent that the UV radiation increases by 10% every 1000 meters. A period with the longest day and sunshine was selected - (16 - 26.07.2017). In order to maximize the early genetic changes from the above effects and to eliminate the adaptations to altitude, the most suitable model species are albino mice of the ICR strain.

Animals

70 healthy male mice were randomly divided into 2 groups of 35 animals. They were transported to the chosen experimental points - Peak Moussala and the area of the Beli Iskar. To register the daily dose of UV radiation a special sensor was installed on every packing-case. The packing- cases were maintained outdoor at their locations for 12 h for a period of 40 days. On the 15th, 30th and 40th day samples from peripheral blood and bone marrow cells were collected. Measurement of daily solar UV irradiation, environmental temperature and humidity in a high-mountain area (Moussala Peak) during the hottest summer week of 2017.

This study stands out as a novelty in its approach to study the effects of exposure to UV which reaches the dermo-epidermal junction and penetrates deeper to the dermis and hypodermis. For this reason it was assumed that blood vessels and blood cells might also be affected by UV exposure. The results showed a significant dose-dependent increase in Howell-Jolly bodies from 15th to the 40th day of the experiment. Currently, approaches used to evaluate the consequences of UV irradiation and gamma background involve also the assessment of genotoxic damage and other cell-detrimental effects on organisms. The study opens up the possibility of more detailed research on the negative combined action of UV on the health of living beings.
