Recall Insight

This recall's affected scope, documented in the Recall Profile below, stays within a single-region or limited-distribution footprint.

Product description

PTW UNIDOS webline: 1) REF T10023, 2) REF T10022 and 3) REF T10023 Firmware version 2.05. Dosimeter for radiation therapy, diagnostic radiology and health physics.

Reason for recall

In some cases, especially with high dose-per-pulse-rates typical for particle (specifically proton) therapy, measuring errors can result. Individual measurement intervals can be lost that are not visible to the user when there is a high dose-per-pulse rate resulting in a too-low dose being displayed on the monitor. This could result in a radiation over-exposure.
