Abstract
Radon (Rn) is a polluting gas coming from radioactive decays and it is not
detectable by human senses as it is colourless, tasteless and odourless. Apart
from the underground position of radioactive sources of such gas, it is able to
cover very long paths through subsoil and to the surface at considerable
distances from the underground starting points. Whenever it surfaces in the
interior of buildings, passing through foundation structures, then it produces a sly
pollution as its presence will be discovered only when it has harmed people.
Owing to previous peculiarities, there is a considerable health risk in the case of
such indoor air pollution and this risk can be mitigated only by precautionary
measures as are used to periodically control Radon concentrations in indoor
environments which are suspected to be polluted by Radon and then to set in
action some techniques to reduce indoor radon concentration in polluted
buildings. Beginning to face the Radon problem, the Province of Ragusa (Italy)
set in action experimental research to discover the real concentrations of Radon
in some public buildings in Ragusa town (ex IPAI building), Modica Town
(technical Institute \“Archimede”) and Scicli Town (Civil Protection Agency
Building). For reasons of space the aim of paper is to show results only for the
IPAI building:
- The techniques and the equipment used to survey the gas
concentrations.
- The analysis of results of the campaign of measurements that permit
one to point out the reliability of methods as a function of the kinds of
equipment.
- The proposed techniques of mitigation of pollution.
Keywords: radon, indoor pollution, measurements and control.
Keywords
