Innovative precision dosimetry solutions by DOSEmappers™

DOSEmappers™ represent a groundbreaking family of dosimetry systems, incorporating miniature silica bead TLDs precisely arranged on a flexible thread. These micro-sensors are specifically designed to capture and retain radiation exposure data, providing a highly adaptable and accurate approach to dose measurement.
Each bead, measuring between 1–2 mm, can be configured in a continuous chain or spaced at tailored intervals to meet diverse application requirements. With a measurement accuracy of ±3% (SD=2), DOSEmappers™ are available in various types and sizes, each optimised for specific dosimetry needs.
The innovative, flexible design enables seamless integration with existing medical and industrial systems, delivering precise dose monitoring in environments previously considered inaccessible or complex. TRUEinvivo® offers reading service where each bead is read individually in a specific sequence, ensuring accurate dose data collection. The results are compiled into a detailed, professional spreadsheet for advanced analysis and reporting.

Bespoke products for every challenge
