RadTarge-W | Electronic Personal Dosimeter is a next-generation all-digital electronic personal dosimeter that combines four functions in one:

  • Dose Equivalent Rate Meter
  • Accumulated Dose Meter
  • Active Self-Reading Dose Meter
  • Active Self-Alarming Dose Meter

This pager-like, direct-reading EPD accurately detects and measures radiation exposure for workers and responders in potentially hazardous environments.

RadTarge II D900 | Electronic Personal Dosimeter uses a YSO scintillation detector combined with a state-of-the-art silicon photomultiplier (YSO+SiPM) and multi-voltage threshold (MVT) algorithm to detect a wide range of radiation doses.

Proportional, real-time detection and measurement provide meaningful readouts that focus on the awareness and safety of the user during critical times. The fast response and wide dose rate range maximize the safety of your team. Intuitive, menu-driven navigation allows users to adjust settings in the field.

A blue acrylic tamper-proof label prevents users from opening the instrument, thus ensuring operational integrity for compliance and liability concerns.

RadTarge-W | Electronic Personal Dosimeter is designed to process routine personnel dosimetry on which occupational dose of records are based.

Dental Office
Over time, even low levels of ionizing radiation from X-Ray machines present potential health hazards. Although dental technicians or hygienists may stand outside the examination room during X-Ray administration, the risk of overexposure still exists and should be monitored to ensure the health of your employees. X-Z LAB’s RadTarge II D900 can give your staff real-time protection.

Veterinary Practice
Extra care is required in X-Raying animals because human intervention is needed. Therefore, the possibility of radiation exposure is higher than in other medical practices. The best way to monitor radiation is with reliable, quality radiation monitoring services from X-Z LAB. Use X-Z LAB’s RadTarge II D900 to know the cumulative exposure levels of your employees to ensure their safety.

The multitudes of diagnostic equipment in the modern hospital environment have varying levels of radiation exposure risks. For example, hospital staff in radiation oncology and radiology departments need to accurately measure the dose of radiation they receive while working near medical equipment containing radioisotopes, and to ensure that the radioactive sources in the equipment are not leaking and emitting hazardous radiation levels. X-Z LAB’s RadTarge II D900 ensures that you assess risk levels appropriately and that the proper dosimetry monitoring is implemented in a cost-efficient manner.

Radiological Center
X-Ray or diagnostic equipment in your office have varying levels of radiation exposure risks. X-Z LAB’s dosimetry solutions can ensure that you assess risk levels appropriately and that the proper dosimetry monitoring is implemented in a cost-efficient manner.

High-Energy Physics
The important work performed at national laboratories and universities often encompasses the risk for exposure to ionizing radiation. Scientists and research assistants working directly in these environments need to be aware of exposure levels on a regular basis. X-Z LAB’s RadTarge II D900 ensures that you assess risk levels appropriately and that the proper dosimetry monitoring is implemented in a cost-efficient manner.
