The basis of our quality is the excellent high purity carrier free 57Co
produced at the Obninsk
Cyclotron Accelerator and more than 30 years of experience in producing
Mössbauer sources
Specific activity: 7500 mCi/mg (!)
Low level impurities: the total content of radioactive impurities (56Co
+ 58Co) does not exceed 0,2% (optionally 0,05%)
Activities available: 5 mCi, 10 mCi, 25 mCi, 50 mCi, 100 mCi, 270 mCi
(Mars-Phobos Type). Other activities on request
Matrix materials: rhodium (chromium, palladium, copper, platinum)
SOURCE HOLDERS
AND APPLICATION
All types of source holders are hermetically
sealed and tested according to the international standards ISO 9978 and
ISO 2919.
