In order to calibrate a gamma-ray spectrometer for radioactivity measurements in environmental samples, it is essential to use standard radioactive sources in the appropriate geometrical configuration. However, the lack of standard sample due to any reason would necessitate the use of reference materials as reliable alternative. They often appear in many matrices and densities. Accordingly, special attention should be drawn towards optimizing the calibration. This work studies the errors encountered because of the attenuation process due to the density difference of the samples (including reference samples) aliquots with identical matrix contents. The highest effect was noticed in the lower energy regions. This study suggests that even for the reference samples with the same matrix, it is necessary to set a recommended density for the measurement process to avoid the errors due to the attenuation. If this is not practically possible it is recommended that attenuation correction due to matrix contents followed by another correction due to density correction would be a reliable approach to reach an optimum calibrating condition.
