Several new materials have been developed for use in the microbiology lab. These materials must be sterilized before use, but cannot withstand a temperature over 60oC and can’t be exposed to water. Which method of sterilization would be applicable?

Ionizing radiation

Explanation:

Ionizing radiation is a method of sterilization that can be used to sterilze material that can not withstand some higher temperature and cannot be exposed to water for sterilization.

It is form of energy that is released when atoms is released to move in the form of electromagnetic waves or particles. such as; X-rays or Gamma rays particles,neutrons, alpha or beta.

It could be dangerous if atoms inliving cells is exposed to it because the cell will be ionized, and it can lead to death of cell , or the mutatation of cell and can lead to cancer. Although not all cells are affected by ionizing radiation.

1)X-Rays, X-rays move in the form of photons energy .

2)Alpha Particles. Alpha particles have less penetration than gamma ray they don't penetrate skin as x-rays

3)Beta Particles, they are particles of electrons which are faster than alpha particles.
