ED3 Extremity Dosimeter


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.  

The ED3 Active Extremity Dosimeter provides monitoring of Hp(0.07) for high energy betas and photons (gammas and X-rays) on the extremities.

Probes come pre-calibrated and are interchangeable on the ED3 electronics unit.
