Gamma Inert Sterilization: A Solution to Polyethylene Oxidation?

Sterilization by Gamma Irradiation

Sterilization is defined as any process that effectively kills or eliminates almost all microorganisms like fungi, bacteria, viruses, spore forms. There are many different sterilization methods depending on the purpose of the sterilization and the material that will be sterilized. The choice of the sterilization method alters depending on materials and devices for giving no harm. These steriliz...

Sterilization Methods and the Comparison of E-Beam Sterilization with Gamma Radiation Sterilization

Sterilization is used in a varity of industry field and a strictly required process for some products used in sterile regions of the body like some medical devices and parenteral drugs. Although there are many kinds of sterilization methods according to physicochemical properties of the substances, the use of radiation in sterilization has many advantages depending on its substantially less tox...

The influence of oxidation on space charge formation in gamma-irradiated low-density polyethylene

The research presented in this paper investigates the role of oxidation in the formation of space charge in gammairradiated low-density polyethylene after being electrically stressed under dc voltage. Polyethylene plaques both with and without antioxidant were irradiated up to 500 kGy using a Co gamma source and space charge distributions were measured using the piezoelectric induced pressure w...

Effect of Terminal Gamma Sterilization on Osteoinductivity

Introduction RTI Biologics, Inc. (RTI) currently produces allograft demineralized bone matrix (DBM) paste products that are manufactured under strict aseptic conditions using single donors. All donors are subjected to rigorous screening, prior to processing, to ensure that no transmissible pathogens are present in donor material. In addition, a terminal sterilization procedure has been introduc...
