3. Specific conditioning of fission products (I, Cs)

3.1 Iodine packaging

Iodine is a fission product with several peculiarities to be carefully considered when developing a specific package. Firstly, this element comprises several radioactive isotopes, including ¹²⁹ I, ¹³¹ I and a stable isotope ¹²⁷ I. The ¹³¹ I isotope is produced in small quantities in reactors and has a short half-life (T _1/2 = 8 days), while the ¹²⁹ I isotope has a very long half-life (T _1/2 = 1.6 × 10 ⁷ ...
