Ionizing radiation applications for a sustainable environment: food preservatio...

The use of ionizing gamma radiation is regulated and authorized by international organizations (EU, EFSA, IAEA, FAO, WHO) for industrial radiation processing of several products: medical devices sterilization, materials modification, cultural heritage preservation and food decontamination. Due to the wrong association of irradiated food with radioactive food, several obstacles have to be overcome in order to pr...

Effect of gamma radiation on mycotoxins solutions

Due to the high toxicity of mycotoxins, many methods have been used to reduce or eliminate them from food and feed. Gamma radiation is one technique that has been investigated with some promising results in degradation of some mycotoxins from food. The aim of this study was to clarify the effect of gamma irradiation on aflatoxin B1 (AFB1) aflatoxin B2 (AFB2), aflatoxin G1 (AFG1) and aflatoxin G2 (AFG2), ochatox...

Radiation Technology: Processes and Products - Concepts and Applications, in Ra...

The 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

Radiosterilization 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...
