- Metals are not modified by radiation sterilisation because all the energy is dissipated, without risk of activation
(Ref. : Manual on Radiation Sterilization of Medical and Biological Materials, Technical Reports series n°149, p.182, IAEA, Vienna, 1973).
- Metals do not adsorb ethylene oxide (Ref.: Sterilisation of biomaterials and medical devices, edited by Sophie Lerouge and Anne Simmons, WP Woodhead Publishing, 2012).
