On the Relationship between Hard Cosmic Ray Flux Decrease and Trauma Leaps in 2007–2009 in Vilnius City, in in The 8th International Conference “Environmental Engineering”: Selected papers. Ed. by D.

Abstract: Relationship between hard cosmic ray flux (HCRF) decrease and traumas number leaps in 1 – 3 days is presented. HCRF 105000 measurement results are compared with trauma leaps in Vilnius in 2007 – 2009. It is found that monthly average data of HCRF and trauma numbers have an opposite correlation. To analyse obtained results of HCRF, the criterion of 200 imp/h decrease during 4 h and more was proposed, while increasing the trauma numbers exceeded monthly average values by 10, 15, 20 %. The efficiency of prognosis of trauma leaps in 1 – 2 days is higher, than in 2 – 3 days after HCRF decrease. Efficiency of relationship between HCRF decrease and traumas number leaps in 1 – 2 days was from 64 to 93 % and 2 – 3 days – from 52 to 65 % in 2007 – 2009. Analysing this relationship an influence of human factor was taken into consideration, because trauma maximum values were registered at the weekends.
