1. (a) What two types of radiation are used for sterilization of medical devices?

(b) Which of these two might pose a problem for polymer materials and why?

(c) During the sterilization process, which one poses the highest danger to human health and why?

Solution

Ques-1:

a) What two types of radiation are used for sterilization of medical devices?

Answer:

UV-irradiation method of sterilization

Gamma rays-irradiation method of sterilization

Electron-Beam Sterilization methods

The medical devices are sensitive to high temperature and low hydyolytic stability due to low melting temperature. Therefore, it is crucial to proceed for sterilization using either Cobalt-60 gamma irradiation or electron-Beam sterilization method

Ques-2: (b) Which of these two might pose a problem for polymer materials and why?

Electron beam direct irradiation, steam sterilization and dry heat sterilization process for polymer material may induce changes in the structure of the products result in complete denaturation of polymer packaging finally biological or medication product may denaturate at these sterilization temperatures

Ques-3:

UV-light irradiation exposure may cause higher level of mutations in human genome result in higher chance of incidence of cancer with ill health
