  To go to Kitchen Radiation Water Filters in the store:  Radiation Filters.

We have in stock, kitchen filters optimized to remove all of the types of radiated contaminants.  They combine 5 types of filter media, each which selects for one type of radiated contaminant.   

The filters work on radiated iodine, cesium, strontium, plutonium, uranium, and other radiated contaminants.


The materials combined in this cartridge use only materials proven over many years to effectively removed radiated materials.  These are each separated by a sediment filter.  These have primarily in the past been used in industrial settings.  Here they are combined into what we believe is the most effective radiation protection you can get in a 10 inch cartridge.  Should you wish to increase protection, you can put 2 or even 3 of these cartridges in line in one of our undercounter or countertop 2 or 3 canister kitchen filters.

  • Carbon particularly works on radiated iodine.  There are carbon beds to start and finish the cartridge.
  • The second bed is resin which selects for Cesium and Strontium.  This uses ion exchange.
  • The third is a mixed bed, using ionic exchange, with two resins, one which selects for cationic ions and the other for anionic ions.  (Anionic have more electrons than protons giving it a negative electronic charge.  Cationic are positively-charged ions.) This  bed works on plutonium, uranium, and other radiation contaminants.


Scientists have used activated carbon to remove iodine-131 from the liquid fuel for nuclear solution reactors.   Activated carbon works by absorbing contaminants, and fixing them, as water passes through it.  It can eventually reach load capacity and cease to absorb new contaminants.  (So change cartridges once a year.  Or if radiation has spiked in your area, more often.  All 'classic' filtration media gets used up over time and should be replaced periodically.)


The EPA also recommends ion exchange for removing radioactive compounds from drinking water.  Ion exchange removes contaminants when water passes through resins.   Those resins readily exchange ions with contaminants.  These cartridges include a combination of resins that work on the different radiated compounds.  Ion exchange was used to clean up legacy nuclear waste from an old reactor at the Department of Energy’s Savannah River Site.

We all love to know how much of anything is filtered out.  That's natural enough.  Unfortunately, it's not real to state specific percentages.  It will depend upon the overall level of radiation, the chemical mix and the comparative levels.  As the chemist who put these together said:  "Capacities are chemistry driven." 

What these cartridges are is the best combination of materials known to be extremely effective against radiation contamination available.  Between them, the media work on all radiated compounds found in water.  How much will be removed will of course depend on the levels of radiation they face, the flow rate of water (slower water flow means more filtration) and whether the contaminants are all of one type, or spread over the range.  Water chemistry is complicated and ever-changing.

What you can, and we submit should, always do is get as much of the right filter material working for you as you can.  More of the right filter materials means a higher level of protection.

What some customers are doing is keeping one or more radiation filters on hand, to put into their kitchen filters (they fit all we sell) in the event of emergency.  Fluoride and chloramine and others such things found in the water can cause health risks over time.  The more you ingest, the higher the risk.  Radiation can peak and decrease more quickly. 

We have seen other radiation filters that will do a lot of good.  This is the only one we've found that has the materials needed to filter both positively- and negatively-charged radioactive particles.
