Radioactive 137Cs (t1/2 = 30.17 years) and 134Cs (t1/2 = 2.06 years) were released in the Chernobyl disaster 30 years ago. Both isotopes primarily decay via ß emission. (i) (ii) (iii) (iv) Predict the product of the nuclear decay of 137 Cs. 137 Cs Calculate.how long it will take for the radioactivity from the isotope to reduce to 1% of its original value. Calculate the % of 134 Cs that persists 30 yrs following the Chernobyl accident. Explain how radioactive Cs gets into the food chain and why this may be a problem.
