Source type PGL. 3 (Ge-68).

(TU 95 2702-2007)

     The standard source of positron radiation is a chamber made of VT1-0 titanium alloy, with an output window made of VT1-0 titanium alloy foil (δ=10 μm). Inside the chamber, sealed by laser welding, there is an active part in the form of a platinum substrate coated with germanium-68 radionuclide.

    By agreement with the customer, the exit window can be made of radiation-resistant lavsan (Kapton) with a thickness of 10 μm. Source activity - up to 20 mCi (0.74 GBq).

PGL.3 type source. 3 (Ti-44 or Ge-68).

(TU 95 2702-2007)

    The double-sided positron radiation source is a chamber (material - titanium alloy VT1-0) made of two identical laser-welded halves, equipped with exit windows made of foil 10 µm thick. Inside the chamber, hermetically sealed laser-welded, there is an active part in the form of titanium-44 or germanium-68 radionuclides deposited on the internal surfaces of the output windows. The activity of the source for germanium-68 is up to 20 mCi (0.74 GBq), and for titanium-44 - up to 0.2 mCi (0.0074 GBq).

    By agreement with the customer, the diameter of the active part of the sources, as well as the overall dimensions of the source chamber, can be changed.

    The PGL.3 sources according to strength classes according to GOST-25926 and ISO-2919 correspond (have the designation) C 21211. The tightness of the source corresponds to GOST R 51119-2002 (ISO 9978-92).
