Construction products. Assessment of release of dangerous substances. Radiation from construction products. Dose assessment of emitted gamma radiation has-tracked-changes 3 Verification of energy efficiency1 Scope The aim of this Technical Report is to propose a methodology to determine indoor gamma dose from building materials and to help classify such a product as required in the Construction Products Regulation [7]. This first technical approach could be a precursor for the development of a harmonized European Standard based on this methodology. NOTE 1 In this Technical Report, doses from radon and thoron exhalation are excluded. However, in 3. 3,
