    abstract = "Ytong is a widely used building material. The X-ray attenuation
properties of Ytong for broad beam geometry conditions and for tube
potentials in the 50-140 kVp range are investigated. Comparisons with
published data for concrete and other building materials are made. The
results suggest that Ytong is not suitable for primary X-ray shielding
in common diagnostic installations. However, walls of Ytong, typically
15-20 cm thick, may offer adequate protection in dental and mammography
installations, as well as in low workload diagnostic installations as a
secondary barrier."
