Radioactivity services

Radioactive air filters

Calibrating monitoring equipment

Radioactive air filters are used to calibrate detector systems used by air monitoring stations and laboratories. We can provide various filter types including 3M, RASA, CINDERELLA/ARAME and SPALAX. These can be in both full or half geometries. 

The filters are spiked with the standard NPL mixed radionuclide solution, with the optional addition of a 210Pb solution. Filters are nominally 5-10 kBq total activity.  

NPL can also provide non-standard filters, please contact us if you have other specific requirements.
