Open Face Charcoal Canisters: The open face charcoal canister has been calibrated at our laboratory for a two to four day exposure with a recommended exposure of two to three days. Humidity effects are controlled by correcting for moisture gain during analysis.
Specifications: The canister is all metal of the Ellisco type of eight ounce capacity. The nominal dimensions of the canister are 4 inches in diameter and1 1/2 inches deep. The canister contains 70 +/- 1 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 - 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 - 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.
Analysis: 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).
