Portable Radioactive Particulate Sampler
Easy to carry and use grab sampler for radioactive particulates in work areas
Grab samples are routinely taken in radio-active laboratories and plants handling radioactive materials to ascertain if any radioactive material got released into the air in those work areas. The grab sample is collected on a filter paper which is subsequently examined with a counting system comprising a radioactivity detector probe and the allied electronics.
Available Models : PSI – PHVS 1, PSI – PHVS 2
Applications
- Work place monitoring in nuclear research and nuclear power plants.
- Emergency monitoring for radioactive leaks.
- Radiation worker health monitoring
- Uranium explorations
- Research and Educational Institutes
Salient Features
- Can be used in both indoor as well as outdoor applications.
- Works well for both spot as well as continuous sampling
- Portable and lightweight
- Flow range available is 200 to 2000 LPM free flow.
- Standard circular filter holder for 101 mm dia filter paper and option of 203x254mm rectangular filter paper holder.
- Low noise imported blower.
Physical Design Highlights :
Polltech’s sampler PSI–PHVS-1 & PSI–PHVS-2 are designed to carry out the task of taking the grab sample. Each of these models comprises a high capacity blower and a filter holder which houses the filter paper. Standard size of the filter holder is 4’’ diameter while 8”x10” rectangular filter paper holder is available on special request. In both the models, the flow can be set, controlled and read.
PSI–PHVS1 includes a rotameter for reading the flow. PSI–PHVS-2 is far more sophisticated as it provides automatically controlled constant flow with high accuracy and stability through the electronic control module which also provides accurate digital display of volume and time in addition to flow.
