Monitoring the lens of the eye (LOE) is extremely important when handling radiopharmaceuticals, in cardiology, oncology and in glove box work as whole-body dose may underestimate the LOE dose, especially when there are high dose gradients.
The ED3 Active Eye Dosimeter provides monitoring of Hp(3) for photons (gammas and X-rays) to the eye.
Probes come pre-calibrated and are interchangeable on the ED3 electronics unit.
