Probable nature of Chizhevsky's «Z-factor» on example of a rare solar event

摘要

The results of the ambulance call data analysis, during one of the most powerful disturbances in the history of geomagnetic disturbances observations in 2003 are presented. The effect of the X-rays flux and the local geomagnetic disturbances in Tomsk on the ambulance calls frequency was investigated. It was found that patients with diseases of the cardiovascular and central nervous systems are characterized by a high sensitivity to variations of heliogeophysical parameters. It was found that variations of epidemiological indicators related both to the influence of geomagnetic perturbations every, and the influence of the X-ray flux absorbed by the Earth's atmosphere.
