Gamma rays are very penetrating and are commonly used for sterilization of disposable medical equipment, such as syringes, needles, cannulas and IV sets. Electromagnetic or particulate radiation can be energetic enough to ionize atoms or molecules ( ionizing radiation ), or less energetic ( non-ionizing radiation ). The temperature of the heat and duration of heating are the factors that affect the extent of sterilization.In heat sterilization process, the longer the exposure to heat the better is the sterilization at a given temperature. Ionizing Radiation 4.3. This is the most common method of sterilization. Usually the sterilization dose must represent a sterility assurance level (SAL) of 10-6, which is a one in 1 million probability of a nonsterile product. For powders and other dry forms, it is a hot air oven if thermostable or gaseous methods and radiation. Other sterilization methods include filtration, ionizing radiation (gamma and electron-beam radiation), and gas (ethylene oxide, formaldehyde). One way in which sterilization by way of irradiation may occur is when ionizing radiation is used. To prevent microbial contamination due to air. The gamma sterilization process uses Cobalt 60 radiation to kill microorganisms on a variety of different products. Incineration 2. Sterilization.

In that many medicinal products and packaging materials are radiation-sensitive, this method is permissible only when the absence of deleterious effects on the material/product has been confirmed prior to use. Sterilization by Rediation. Even if physical methods of sterilization are more appropriate for effective sterilization, it is not always appropriate to use for heat-sensitive materials like plastics, fiber optics, and biological specimens. Methods of Sterilization in hospitals are for metallic surgical instruments boiling, autoclave, incineration can be done. Elimination of Condensate 6. And in 1898 Marie and Pierre Curie discovered several radioactive elements and first used the term “radioactive.” Marie received the Nobel prize twice in two different scientific disciplines even though she suffered from a blood illness attributed to prolong… There are 2 general types of radiation used for sterilization, ionizing radiation and non-ionizing radiation. The sterilization processes most commonly used by medical device manufacturers are ethylene oxide and radiation. Sterilization Using Ionizing Radiation. 64 ... Gamma radiation sterilization of medical device is common but irradiation effect at 2.5 mega rad on a bone replacement material when started and modified property when investigated by Creep test. Radiochemical sterilization (RCS) is an emerging technology. Sterilization can be achieved using electromagnetic radiation, such as Ultraviolet light, X-rays and gamma rays, or irradiation by subatomic particles such as by electron beams. This is due in part to the availability of equipment for large-scale processing and the flexibility of application of these processes to a wide variety of products and packaging. No SlideShare. 5. An emerging method. A Radiation Sterilization Validation is used to determine the appropriate sterilization dose for a product. It involves the application of heat/chemical on the substance like drugs, food, surgical equipment, nutraceuticals etc. Ionizing radiation is the use of short wavelength, high-intensity radiation to destroy microorganisms. A yearly total of some 700 tons of irradiated (2.5 Mrad) laboratory animal diet is sold, enough to feed 180 000 rats or 900 000 mice per annum on a totally Steam also continues to play a significant role. 4. Sterilization by ionizing radiation, primarily by cobalt 60 gamma rays or electron accelerators, is a low-temperature sterilization method that has been used for a number of medical products (e.g., tissue for transplantation, pharmaceuticals, medical devices). Flaming 4. Radiation is commonly employed for sterilizing heat sensitive materials such as disposable plastic products and materials that cannot withstand moisture.. Best suited for high volumes. The heat used kills the microbes in the substance. Heat sterilization: Heat is the most widely used sterilization … – Customized solutions (modified atmospheres). – In 1896 Henri Becquerel observed radiation emitted from uranium. Chemical Sterilization is the process of removal of microorganisms by the use of chemical bactericidal agents. ISO 11137-3:2017 gives guidance on meeting the requirements in ISO 11137-1 and ISO 11137-2 and in ISO/TS 13004 relating to dosimetry and its use in development, validation and routine control of a radiation sterilization process. Commercial radiation sterilization has existed since the late 1950s and has grown tremendously in popularity over the last 60 years. Radiation sterilization of medical products also is currently regulated by two standards, EN 552 (1994) and ISO 11137 (1995). Radiation sterilization of animal food (mainly for laboratory animals) is an established practice in several countries (Australia, Austria, Canada, France, Israel, Japan, the Netherlands, UK). Radiation sterilization is used mainly for the sterilization of heat sensitive materials and products. Ethylene oxide gas, Plasma gas, Chlorine dioxide, Nitrogen Dioxide, Ozone, Hydrogen Peroxide, Glutaraldehyde and formaldehyde, Peracetic acid, Radiation sterilization (electron beams, X-rays, gamma rays, or irradiation by subatomic particles), Moist heat in autoclaves, Dry-heat in ovens. Red heat 3. It will be of value to those Validation of Sterilization 7. processes both dry and moist heat are used for sterilization. Processing with gamma irradiation yields quick turnaround time, easily penetrating packaging and product, and is ideal for many types of materials. The devices used to do this are called irradiators and generally contain a gamma-emitting sealed source or sources.
