The RADēCO™ Models RL-100 and RL-300 Radioiodine Samplers are special sampling cartridges specifically designed for the evaluation of airborne concentrations of elemental radioiodine, organic radionuclides, and other radioiodine compounds.
The RADēCO™ Models RL-100 and RL-300 Radioiodine Samplers are special sampling cartridges specifically designed for the evaluation of airborne concentrations of elemental radioiodine, organic radionuclides, and other radioiodine compounds. They are composed of selected 5% TEDA treated charcoal packaged in a plastic case.
Each batch of Model RL-100 and RL-300 cartridges is manufactured from pre-tested charcoal. After loading the material into the cartridges, random sample cartridges are selected and subjected to stringent radioiodine testing procedures. An independent laboratory develops a Certificate of Performance assuring the user of the quality of the product. This certificate is included with each purchase.
The Model RL-100 Radioiodine Sampler utilizes 40×50 mesh charcoal and is designed for very high collection efficiency at high flow rates for long term sampling. The Model RL-300 Radioiodine Sampler uses 20x 30 mesh charcoal and is designed for use at low flow sampling operations.
These cartridges are routinely used in-line and downstream of a high efficiency filter which will remove radioactive particulates which can interfere with the radioiodine measurement. Filter papers and combination pre-filter and cartridge sample holders are available as accessories for the RADēCO air samplers.
CAUTION: Radioiodine Samplers must not be used in personal respirators for breathing protection.

*Rounded to whole % -These collection efficiencies may vary slightly from batch to batch.
Testing
RADēCO™ cartridges are tested by an outside independent laboratory. Twenty-five (25) separate test measurements (or more) are utilized to produce our Certificate of Performance. These tests certify the retention efficiencies of methyl iodide at 30 C and 95% RH in accordance with ASTM D-
3803-89, Sect 12
Labeling : Each Cartridge has shelf life data on label
Calibration Material
Methyl Iodide—This is the most difficult of the organic iodides to collect for analysis. The collection efficiency for other radionuclides will be higher.
Shelf Life
The RL-100 and RL-300 cartridges are packed in sleeves of 20 cartridges each. Each sleeve is of 10 mil plastic with the ends heat-sealed. The shelf life is ten years from date of material testing/manufacture. Special individual cartridge packaging is available.
