Radiation Effects
Ionising radiation is found across
a wide range of applications, from nuclear to space, through to
numerous industrial processes. Applied Sterilisation
Technologies (AST) provides a comprehensive selection of
radiation testing facilities and services, based upon our
unrivalled portfolio of irradiation plants across Europe, Africa
and Asia.

Our Facilities
The assessment of radiation effects on materials and components
normally considers several aspects of the radiation environment in
turn. Isotron (AST) offers test facilities for total dose,
electrons and protons as follows:
- Total integrated dose: gamma radiation from cobalt-60 sources;
dose rates from background to several kGy/hr (depending on sample
size); in-situ monitoring, temperature control
- Electron irradiation: from 1 to 20 MeV; doses from tens of Gy
to MGy; in-situ monitoring; temperature control; sample handling by
conveyor or static positioning under the beam (forced cooling
required).
- Proton irradiation: from 0.5 to 10 MeV; irradiation in vacuum
or air; in-situ monitoring, temperature control; ISO Class 7 (class
10,000) clean room available.
- Helium ion (alpha) irradiation: from 0.5 to 15 MeV; irradiation
in vacuum or air in-situ monitoring, temperature control; ISO Class
7 (class 10,000) clean room available.
The synergistic effect of
irradiation and other factors can lead to more rapid degradation
than the sum of the individual effects would indicate. We offer the
possibility to irradiate in a range of gaseous environments and
vacuum, with heating or cooling, with or without electrical stress
and, for solar cells, under illumination. All our plants
offer dosimetry traceable to national standards.
