Cosmic ray dose rate measurements were performed inside 25 reinforced concrete castle towers using a NaI(Tl) scintillation spectrometer. Approximating the shape of each tower with a multi-cylinder, a bulk density was calculated using inside/outside ratio of dose rate. The evaluated bulk density was multiplied by the volume of the tower to obtain its weight. The data of each tower necessary for analyses were elevation, total floor space, volume, outside and inside dose rates. Those data were listed along with the corresponding calculated bulk density and weight.

Key words: cosmic ray; dose rate; NaI(Tl) scintillation detector; concrete; castle tower; bulk density; weight
