4 Way Personnel Tritium-In-Air Monitor
Model 7020-4
Performs tritium-in-air monitoring directly around a seated operator or maintainer located in a potentially tritium-active location or performing tasks which could result in tritium release.
- Convenient tritium-in-air monitoring.
- Easily moved.
- Simultaneously monitors four locations.
- Can be placed close to the source of measurement.
- Measures to 1 µCi/m³.
- Provides permanent record.
- Bubbler check measurement.
The 4-way tritium-in-air monitoring device comprises two of Tyne’s 7000 tritium monitor controllers mounted on a movable hand cart. This can be pushed to an environment where an operator is performing tasks where concerns of possible tritium leaks into the atmosphere exist.
Four tubes held in lab clamps are placed strategically at locations of greatest concern. Each tube draws air from the chosen location. Flow is set using a rotameter, and is monitored for tritium by passing it through one of four ion chambers. The gas is then passed through a bubbler before being discharge back into the room. The bubbler contents will be analyzed using liquid scintillation counting.
The ion chambers enable accurate measurement and the bubblers provide long term monitoring of the reliability of the ion chambers. The atmosphere is pumped into the ion chambers via a vacuum pump. The ion chambers are Tyne’s 1000 cc chambers noted for their accuracy and reliability. The controller can be set to alarm on high level.
Tyne’s ion chamber controllers are mounted in the mobile cart to provide a compact and manageable unit. The controllers each have two channels and can therefore simultaneously serve two ion chambers so only two controllers are required for four check sites.
Each ion chamber can be set to alarm if tritium is detected. Using the computer program which Tyne makes available with its controller, readings can be permanently recorded.
The cart is fitted with easy ride, heavy duty tires to protect the equipment from shock during trasportation. The cart is manufactured from aluminum and stainless steel. This allows easy relocation to areas requiring tritium-in-air monitoring.
Bubblers are readily accessible and can be removed by twisting from the threaded lid for water measurement by scintillation counter.

Determines the amount of tritium in the laboratory atmosphere via concentration of tritium absorbed into the Passive Diffusion Cell.
Tyne's tritium bubbler system collects workspace or environmental samples from ambient air. With the recognized fast conversion dynamic of free tritium to THO, the requirement for a catalytic furnace to convert free Tritium into THO prior to sampling is avoided and a direct three stage bubbler system implemented.
In order to provide customers with the desired flexibility, Tyne Engineering has developed an external pump box that can be utilized with all of our tritium monitoring instruments, providing reliable, continuous, long term operation beyond the design life of the instrument internal pumps.desired.
This system was designed by Tyne for the capture of tritium and carbon-14 from biological and environmental samples by pyrolysis followed by high temperature catalysis to THO and CO2. The evolved gases are captured in bubblers for THO capture followed by bubblers for CO2 capture. The resulting bubbler samples are analyzed using a laboratory liquid scintillation counter.
