Radiation Technology: Processes and Products - Concepts and Applications, in Ra...
Cabo Verde, Sandra; Melo, Rita; Marcos, Helena; Nunes, Inês; Dores, Vânia; António, Amilcar; Reis, Joana; Teubig, Pamela; Santos, PedroThe basic concepts presented in this chapter are connected with the application of ionizing radiation on microorganisms and its effects that’s enable its use for processes and products in Industry. The radiation technology process is based on the physics and chemistry of radiation interactions with matter and the quantities that are used for monitoring radiation energy depositions. The modifications in a materi...
Sterilization of an Electronical Medical Device
Reis, Joana; Cabo Verde, Sandra; Capela Silva, Fernando; Potes, José; Melo, Rita; Nunes, Inês; Marcos, Helena; Silva, Telma; Botelho, Maria LuísaRadiosterilization was applied to a medical device with a “programmable memory” to allow in vivo implantation. Irradiation on a Cobalt-60 facility at 25 kGy at a dose rate of 2kGy/h corrupted the memory. Therefore an alternative sterilization method using UV was developed and validated based on ISO 11737-1 and ISO 14937. These procedures may be useful and effective for research purposes when only a small number...
