Irradiation sources

for irradiations from room temperature up to 500 °C.

lexsyg research TL/ OSL reader can be equipped with up to two irradiation units for irradiations from room temperature up to 500 °C.

  • To irradiate samples for TL, OSL etc. and for RF measurement.

  • Easy and safe service for regular wipe-test

Beta source

Beta irradiation unit

  • radioisotope: Sr-90; activity: 1.85 GBq;

  • dose rate: about 0.11 Gy/s

  • dose rate variation over the irradiation area: ≤ (± 10 %) @ 8 mm diameter, ≤ (± 12.5 %) @ 10 m diameter

  • maximum energy: ca. 2.2 MeV

Beta source (ring)

  • radioisotope: Sr-90; activity: < 3 GBq;

  • dose rate: about 0.06 Gy/s

  • very homogeneous dose rate over the irradiation area: (± 2.5 %) @ 8 mm diameter; (± 3.5 %) @ 10 mm diameter

  • maximum energy: ca. 2.2 MeV

  • required for Radio Fluorescence (RF) measurements/applications

Alpha source

Alpha irradiation unit

  • radioisotope: Am-241, activity: 20- 30 MBq

  • cover layer: 2 – 4 μm Au

  • active diameter: 21.0 mm (thickness 0.25 mm)

  • alpha/gamma type of radiation

  • maximum Energy: 5.5 MeV/ 60 keV

  • very homogeneous dose rate over irradiation area

X-ray generator

X-ray generator - an alternative to Beta source

  • fully housed X-ray tube for highly homogeneous irradiation

  • fully integrated dose rate live-time monitoring system

  • zero radiation (when not in use)

Technical details

  • target material: Tungsten

  • tube current: 0.1 - 1.0 mA

  • shutter: 5 mm brass

  • absorber: Al, 200 µm (changeable)

  • varian VF-50J (fully housed)
