AB  - Izlaganje sunčevom ultravioletnom (UV) zračenju analizirano je za dve grupe skijaša:
jedna grupa merila je izlaganje tokom 1-7. januara 2017. na skijalištu Stara Planina,
Srbija, a druga od 29. januara do 3. februara 2017. u skijalištu Val Soni, Francuska.
Izlaganje je mereno ličnim monitorima UV zračenja. U Val Soniju, dva monitora merila
su spoljašnje UV zračenje koje je uzeto kao referentna tačka za izmerena lična
izlaganja. Metodom vejvlet transformacije (VT) izračunate su spektralne funkcije
izmerenih podataka kako bi se ustanovili pojedinačni obrasci ponašanja skijaša i nivo
individualne izloženosti UV zračenju. Rezultati ne pokazuju razliku u srednjem nivou
grupne izloženosti na različitim lokacijama, jer se u oba slučaja dobija srednja vrednost
nagiba VT spektra snage signala približno jednaka jedan. Ova vrednost govori o
visokom stepenu izlaganja sunčevom UV zračenju, koja je kod skijaša najverovatnije
posledica dugotrajnog kontinuiranog boravka na suncu. Obrasci ponašanja skijaša,
međutim, pojedinačno se razlikuju u oba skijališta, što se ogleda u nagibu VT
spektralnih funkcija koji se kreće u rasponu od (0,50±0,02) do (1,44±0,02). U VT
spektralnim funkcijama uočeni su karakteristični maksimumi koji mogu da ukažu na
dužinu ukupnog kontinuiranog pojedinačnog izlaganja UV zračenju kod skijaša. Ovaj
kvantitativni podatak može poslužiti u budućim procenama potrebe za korigovanjem
pojedinačnog ponašanja na suncu.
AB  - Exposure to solar ultraviolet (UV) radiation is analysed for two groups of skiers. One
group measured UV exposure over 1-7 January 2017 in the StaraPlanina ski resort in
Serbia, while the other performed measurements between 29 January and 3 February
2017 in the Val Cenis ski resort in France. Exposure was measured using personal UV
monitors. In Val Cenis, two monitors recorded ambient UV radiation which is taken as
a reference point for the measured personal exposures. To establish personal patterns
of behaviour and a level of individual exposure to solar UV, wavelet transform (WT) is
used to calculate spectral functions of the obtained data. The results show no significant
difference in the mean levels of group exposure at different locations, as the mean slope
of the WT spectra is approximately one in both cases. This value implies a high UV
exposure which most likely results from prolonged periods of time spent in the sun. On
the other hand, the individual slopes of the WT spectral functions range between
(0.50±0.02) and (1.44±0.02), and thusindicate personal differences in behavioural
patterns of the skiers. Further, the WT spectral functions show characteristic peaks that
demonstrate the duration of the total continual individual UV exposure in skiers, and
this result could be used in future assessments and recommendations for modification of
personal behaviour in the sun.

AB  - Dependence of the lead-210 activity concentration in surface air on meteorological variables and teleconnection indices is investigated using multivariate analysis, which gives the Boosted Decision Trees method as the most suitable for variable analysis. A mapped functional behaviour of the lead-210 activity concentration is further obtained, and used to test predictability of lead-210 in surface air. The results show an agreement between the predicted and measured values. The temporal evolution of the measured activities is satisfactorily matched by the prediction. The largest qualitative differences are obtained for winter months.
