Problem 1. The half-life of iodine-125 is 60 days. What is the first order decay rate constant? If we start with 30 g of it, how much is left after 1 year If the decay was alpha radiation, what would iodine -125 decay to? If the decay was a beta radiation, what would iodine-125 decay to? (And just FYI, the decay is neither alpha nor beta. I-125 decays via a decay process called 'electron capture', where a proton captures an inner electron to become a neutron. Thus, I-125 actually decays to non-radioactive Te-125. About 7% of its decays produce gamma radiation but most of the energy is emitted as low-energy photons and x-rays. It is often used for radiation therapy for cancer treatment).
