Personal Gamma Radiation Dosimeter

DKG-21 EcotestCARD

EcotestCARD is a direct reading personal dosimeter for personnel exposure monitoring. This dosimeter badge can be used either independently or within the automated system of personal dosimetry control.

In 2011, the Ministry of Emergency Situations of Ukraine sent EcotestCARD dosimeters to Japan as humanitarian aid for recovery from the accident at the Fukushima NPP, where they gained a reputation of a reliable and precise product.
