Can we remove radiation from drinking water?

I have been scouring the internet for articles on radiation and different processes that can be used to possibly rid water of radioactive particles. I found a few sites that had information. Most sites mentioned reverse osmosis being a great tool for this. Does anyone else have any information on this? Are there other ways this can be done, i.e. whole house water systems? Here is the site I referenced for information. Anyone else with other information please paste so we can all look at it. Reverse Osmosis Reviews

How effective is steam distillation with carbon filter

Can anyone with some background in this field comment upon the effectiveness of steam distillation with carbon filter.

Is it better, the same, or not as effective as RO for removing radioactive particles from drinking water?

I have a water distillation system and need to know whether I should change to an RO system.

Radioactivity Concerns in Drinking Water

Multi-Pure Addresses Radioactivity Concerns in Drinking Water as a Result of Damage to the Fukushima Dai-ichi Nuclear Power Plant in Japan.

Andrew Fenwick, PhD, Vice President of Technical Services, Multi-Pure International suggests these resources for concerned customers:

How will radionuclides be removed from my drinking water?
According to the EPA, the following treatment method(s) have proven to be effective in removing radionuclides at levels below their MCLs:

Beta particle and Photon Radiation: ion exchange and reverse osmosis;
(Gross) Alpha Emitters: reverse osmosis;
Radium 226 and Radium 228 (Combined): ion exchange, reverse osmosis, lime softening;
Uranium: Ion exchange, reverse osmosis, lime softening, coagulation/filtration.
Dr. Fenwick has also released this statement:

"Radioactivity (its sources, the decay process, transmission, protection, and disposal) is an unquestionably complex topic.  The information provided here is admittedly, and necessarily, very general.  The largest concern in drinking water after a meltdown is likely the presence of Uranium, although there are many additional sources (Plutonium, Radium, Cesium, etc.).  We do not specifically test for the reduction of these materials, nor are there NSF standards/ protocols.  With that said, heavier radionuclides, like those listed above, are likely reduced with our blocks, specifically those blocks that are certified for lead reduction.

"Three important notes: 1. As always, efficacy and lifetime will depend on several factors (compounds’ unique properties, concentration in the influent water, water chemistry, etc.).  2. In addition to those listed above, several other “daughter” nuclides/ radionuclides (products of the decay process) of various chemistries/ classes will have various reduction efficacies.  Commenting on these is not possible.  3. Unlike other non-radioactive contaminants (Lead, Mercury, Arsenic, VOCs, other organics), removal from the water, and thus concentration in the block, may not be sufficient for the radioactive elements/ compounds.  They continue to emit radiation even when removed/ immobilized.  Based on these issues, and the EPA testing and “endorsement,” reverse osmosis is a more bona fide technology in this case.”

Water treatment

I have an under the sink reverse osmosis system which was installed fairly recently, it includes carbon filters. So, when the nuclear disaster first happened, I called the water company that sold me the system to ask the same questions that you are asking.

The company did some additional research and basically told me this: Reverse osmosis will remove 90-95% of the radioactivity. I believe that the parts that are gaseous will not be completely handled. (Please, don't quote me, this was the gist).

However, to get to virtually 100% pure, which they need to do in some lab applications (BRAWN team can surely comment here), one would need to add a special resin filter. However, that filter will leave the water with a funny taste (if I recall, he described it as "fishy."). So, in order to make that water more palatable, they would have to also add some type of re-mineralization(?)process.

In the end, I decided that, at least for the time being, I would not add the resin filter.

Now, I would still like to see how this compares with a water distiller with a carbon filter, but I have not been able to get that information?
