I really enjoy listening to the Naked Scientists via the podcast from Melbourne Australia. I have a question that has been probably covered by others.

Does distillation of water remove radioactive iodine and caesium?

Do any water filters, such as charcoal, remove radioactive iodine and caesium?

Regards,

Craig Fryer

What do you think?

Distillation will remove caesium. It may or may not remover iodine which occurs in amny forms but, with chlorinated water supplies, the iodine is likely to be present as iodate which isn't volatile so it will be removed by distillation.
Can I ask why you are interested?
Melbourne's water isn't contaminated with Cs or I.

If distillation is not possible then ion exchange using a resin bed will work, at least until the resin is saturated. You could regenerate the resin and get a concentrated Cesium and Iodine solution, but most time the resin would be treated as waste and disposed.
