A modified method is presented for the determination of natural and artificial isotopes in building raws and materials using multichannel gamma-ray spectrometry. A procedure is given for the preparation of standards as well as for the determination of radioisotopes content in typical building raws and/or materials. Results of these determinations were compared with those from standard, tri-channel gamma spectrometry described in Instruction No. 234/95 [2] issued by the Institute of Building Technology in Warsaw, Poland.
