It looks like an isotope notation. "I‑134" (or written as I-134) means the element iodine with mass number 134 — i.e., an iodine atom that has 53 protons and 81 neutrons. That isotope is radioactive.
Brief facts:
- I‑134 is a radioactive iodine isotope with a very short half‑life (about 50–55 minutes).
- It decays by beta emission (and emits gamma rays) to xenon‑134.
- It’s not commonly used in routine medical imaging/therapy (I‑123 and I‑131 are the usual medical isotopes); I‑134 is mainly of interest in nuclear physics and reactor/radiochemistry contexts.
- Because it’s radioactive, it’s a radiation hazard while present, but the short half‑life means it decays away relatively quickly.
If you meant something different (a part number, a line on a form, or a typographical string like "I-134I"), please paste the context and I’ll explain that instead.
