Iodine nuclear stability

Solution. According to the Nuclear Wallet Cards, the only stable isotope of iodine is 1. Therefore, l lies to the higher side of the band of stability and will need to increase Z in order to become a stable isotope. The only form of radioactive decay that increases Z is the emission of a beta particle. Using the principles of conservation of mass number and conservation of atomic number during a nuclear reaction, the nuclear equation for beta decay is... 

Radioactive substances were scattered to the air, sea, and soil by nuclear power plant accident occurred in Japan in March 2011. Large amount of radioactive iodine was thought to be scattered, and might affect the human body, however, practical techniques of collection and safekeeping of the radioactive iodine have not been established yet. Several reports focused on collection and/or immobilization of iodine with MgO and H2O2 [1], bentonite, zeolite [2], apatite [3], and so on, however, these problems are not simple because of solubility, volatility, and low thermal stability of compounds of iodine.
