Product Detail


Red light comment

Ionizing Radiation:  This product may contain fly ash, which falls into the category of Naturally Occurring Radioactive Material (NORM). However its use in building materials has not been shown to raise the level of ionizing radiation above background levels, but it is difficult to be precise because the level of radiation is dependant on the radioactivity of the coal burned.  The USGS has done studies showing that the use of fly ash in building materials does not have substantial effect on the level of radioactive exposure from building materials and natural radiation in the environment when used at the levels possible within carpet.  There may also be an issue with radon gas build up in poorly ventilated buildings, but has not shown to cause substantial levels and harmful effects in normally ventilated buildings (1-3 air changes per hour) according to the Australian Radiation Protection and Nuclear Safety Agency.
