Eternit (асбестоцементный шифер) is absolutely everywhere in Russia, even if banned in residential construction, so the exposure chance is still pretty high.
It is a fact that that type of asbestos is less bad (though still bad). But yes it's true it is common in roofs in russia and probably shouldn't be.
But if roofing material is exposed in your room you're doing something wrong. Also legal limit for asbest dust in air also apply to asbest used in "шифер" (according to wikipedia)
