I was looking at this website which lists various radioisotope products.

Under "Изотоп Иридий-192" (Iridium Isotope-192), it lists several items such as "ГИИД-1". But I can't for the life of me understand what "ГИИД-1" stands for.

The English format of this website is completely different from the Russian one, and I haven't been able to get anything from Google.

Can someone help, please?

It's just a name. And only the authors know what exactly it means. Ask them.
We can only guess:

  • Г - Гамма
  • И - Излучатель
  • И - Иридиевый
  • Д-1 - ???

  • "ИД" stands for "иридий" and "1" is just a model.

  • The table (from the document in the other answer) suggests that Д-1 is a diameter number. Jun 3, 2023 at 13:16

I found this document in a Google search for ГИИД. You can find detailed information on page 9 of the document. ГИИД-1 is a device used as a source of gamma rays in radiography. The device is a steel container with an isotope iridium-192 inside. There are several devices, the first being ГИИД-1.

The meaning of the word ГИИД is explained in another response, but my guess is that it's источник, not излучатель: "Гамма-источник иридиевый", "1" - I think, is just a model number.
