Indoor radon survey in Visegrad countries.

The indoor radon measurements were carried out in 123 residential buildings and 33 schools in Visegrad countries (Slovakia, Hungary and Poland). In 13.2% of rooms radon concentration exceeded 300Bqm(-3), the reference value recommended in the Council Directive 2013/59/EURATOM.

Preliminary results of indoor radon survey in V4 countries.

The measurements of radon activity concentration carried out in residential houses of V4 countries (Hungary, Poland and Slovakia) show that radon levels in these countries considerably exceed the world average. Therefore, the new radon data and statistical analysis are required from these four countries. Each partner chose a region in their own country, where radon concentration in residential buildings was expected to be higher.

The association of carotid artery stenosis with carotid sinus hypersensitivity. Transitory cerebral ischaemic attack provoked by carotid sinus reflex.

The association of internal carotid stenosis with the carotid sinus syndrome represents a special clinical entity. Transitory cerebral ischaemic attack (TIA) will usually be manifested by activation of carotid sinus reflex. Eighteen patients were observed suffering from both carotid sinus hypersensitivity and TIA.
