PLACING THE RADON CANISTER. Canister should be placed in the lowest level of the house that is regularly used for 8-10 hours per week. If making a follow-up measurement, the US EPA recommends placing a canister on each level that is used for living space. Do NOT test in garage, porch, kitchen, closet, bathroom, furnace room, laundry room, root cellar, crawl space or sump. DO NOT place canisters where they will be exposed to high humidity &/or noticeable drafts from open doors, windows, fireplace, heat/air conditioning vents etc. Place each canister at least 3' from exterior doors or windows & at least 2' off the floor. If performing a duplicate test (typically for Real Estate Transactions), place 2 canisters side by side 4" apart. Leave each canister in place & undisturbed for 48-96 hours.

ALL SALES ARE FINAL. No returns will be accepted for these items.


The canister is all metal (Ellisco type), eight ounce capacity. The nominal dimensions of the canister are 4 inches in diameter and 1.5 inches deep. The canister contains approximately 70 grams of Calgon type 1193-coconut shell charcoal. The charcoal is 8 x 16 mesh and has a maximum radioactivity for gamma emitters of 0.2 pCi/g. The charcoal is held firmly in place by a screen of 30 to 50% openness and a borosilicate glass fiber filter with a basis weight of 22.9 grams / square meter. The screen and filter are held in place by an internally expandable ring of sufficient stiffness to hold the charcoal in place during handling including a drop from 3 to 4 feet onto a concrete floor. The canister is covered with a metal lid with a circular piece of foam material attached to the inner surface and sealed with vinyl tape.


Canisters are securely placed within a lead-shielded chamber in contact with a sodium iodide (NaI) crystal. The gamma radiation from the elements adsorbed onto the charcoal causes a light signal in the NaI crystal, which is electrically enhanced and counted using a ratemeter. Background counts are subtracted and the net counts are entered into a formula with other relevant data yielding quantitative results stated in picoCuries per Liter (pCi/L).
