I was looking at this

and can't for the life of me understand what ГИИД-1 means.

The English format of this website is completely different from the Russian one and 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.

  • First И could be источник

I found this document searching on google by ГИИД. You can find detailed information on page 9 of the document. ГИИД-1 is a device, which is 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 is ГИИД-1.

Meaning of the word ГИИД is explained in another answer, but I suppose it would be источник, not излучатель: "Гамма-источник иридиевый", "1" - I think, is just a number of a model.
