The system constructive to keep smartblockplus eps is not harmful to humans and does not have any emission radioactive

All building materials (traditional) have a certain natural radioactivity, in some cases significantly

If the raw materials come from land especially rich in natural radioisotopes such as uranium, thorium and radio. In these cases need to do more careful assessments to ensure that homes within occur excessive concentration of radioactive emissions resulting exhibition risk to humans. To determine if a material has a certain amount of radioactive hazard, the European Union has agreed to an index that measures the concentration of radioactive material on the basis of its content of Thorium, Radio Potassium is:

Materials with I>1 have a radioactivity must not be underestimated. The materials I<0.5 are considered low-radioactive and therefore do not represent a danger to human health.

Tests performed attest that the system constructively to keep eps smartblockplus presents an index of the radioactivity among the lowest ever (0.25) in the traditional building materials (cement blocks, thermo brick of any kind, blocks tuff , granite blocks, etc.) as can be seen from the graph below:
