✦ Synopsis

Various x-ray contrast materials, barium sulphate (BaSO,) and zirconium oxide (ZrO,), were tested for their radioactivity by means of a gamma spectrometer. While BaSO, showed no detectable radiation emission, the ZrOz materials of various makes showed slight to partially high radioactive emission. From all zirconium oxides, only the pharmaceutic agent OPTIPUR@ (MERCK) showed no detectable radioactivity. Taking into account that these x-ray contrast materials remain in the body for decades as components of the bone cement, it would seem prudent to urge cement manufacturers to substitute high purity radiation-free zirconium in place of radioactive zirconium oxide.

## Abstract The effect of varying the initial temperature of the components of poly(methyl methacrylate) (PMMA) bone cement has been investigated. Electron paramagnetic resonance (EPR) spectroscopy was used to monitor free radical decay during the curing of the cement. Samples cured in saline at 37
