MODEL GY-130

The RADeCO Model GY-130 Radioiodine Sampler is a special cartridge specifically designed for the sampling 
of airborne concentrations of radioiodine and other gaseous iodine compounds in the presence of radioactive noble 
gases. Testing indicates that a minimum of radioactive Xenon, Krypton, and other noble gases are retained by the Silver 
Zeolite thereby minimizing their interference with the radioiodine measurement.

Each batch of Silver Zeolite is thoroughly tested prior to cartridge manufacture assuring a high percentage of 
radioiodine capture. A certificate is supplied with each order of cartridges certifying the percent retention of 
radioiodines versus airflow rate through the cartridge.

Routinely, these cartridges are 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 RADeCO accessories.

CAUTION: The Model GY-130 Radioiodine Sampler must not be used in personal respirators for breathing protection.

Features:
2.27" Diameter X 1.04" Thick
Silver Loaded Zeolite
Metal case
Uniform density packed
Certified for Performance-Percent
Retention versus Air Flow Rate and Noble Gas Retention

Calibration Method  
Methyl Iodine-this is the most difficult of the organic iodides to collect for analysis. The collection efficiency for other radioiodides will be higher.

Purge Definition
2 hour purge-After the methyl iodide is collected by the cartridge, air (at the sampling rate) is drawn through the cartridge to strip out the loosely held material.

Storage Life
The BG-300 cartridge are packed in sleeves of 10 cartridges each. Each sleeve is of 10 Mil Plastic with the ends heat-sealed. The shelf life should be indefinite if the pocket in which the cartridges are sealed remains in-tact. Special individual cartridge packaging is available.
