Abstract
IN the course of work on radiation damage to polythene using the Woolwich 4.3 MeV linear accelerator, it was observed that a dose of 1,000 megarep raised the elastic modulus of ‘Alkathene 7’ by a factor of three without apparently affecting crystal content. This was confirmed both by an X-ray diffraction analysis of the material1 and by a spherulite analysis. The density of the material was also found to have increased by 0.95 per cent.
