ED3
Active Extremity Dosimeter
The ED3 Active Extremity Dosimeter provides monitoring of Hp(0.07) for betas and gammas on the extremities.
Monitoring the extremities is extremely important when handling radiopharmaceuticals, in cardiology, oncology and glove box work as whole body dose may underestimate the extremity dose, especially when there are high dose gradients.
Features at a glance
- Real-time readout for 1—2 detectors*
