Why do companies choose electron beam irradiation to sterilize their products?

Electron beam radiation has been used for more than half a century to sterilize medical devices due to several key benefits, including: low cost, high reliability, turnaround time, safety, and relative ease of validation.

Important Parameters of an Electron Beam – Understanding energy (MeV), current (mA) and line speed — and why they matter.

The key parameters to control an electron beam accelerator are the energy, current and line speed of the process. The accelerators used by E-BEAM Services are similar to the old cathode ray tube (CRT) televisions. However, instead of operating at about 25,000 volts, our industrial electron beams can operate at up to 5,000,000 volts. The […]

Can e-beam really penetrate my product – I mean, isn’t it just a surface treatment?

  I have been asked, or even been told, that e-beam is “only a surface treatment and can’t get through any more than a piece of paper.” Wrong. For decades, e-beam has been used to sterilize whole cases of medical devices, such as those in the picture below. Thousands of truckloads are contract-sterilized by e-beam […]

What does “pounds per square foot” mean to me when evaluating e-beam dose penetration?

You may hear the limitation of “up to 8 pounds per square foot” regarding the penetrating capability of a 4.5 MeV accelerator. What does that mean? Start with the image of your box of medical devices on a conveyor going through a shower of electrons raining down on it.
