Product catalog summary
Overview
NanoDot dosimeters are designed for single point radiation assessment and are compatible with the microSTAR®ii reader. They offer complete reanalysis capabilities and require no preparation in clinical settings. The dosimeters feature a labeled sensitivity in their 2D bar code for rapid and accurate readings. LANDAUER's optically stimulated luminescence (OSL) technology, which includes nanoDot dosimeters, provides a universal solution for reducing radiation errors in medical imaging and radiation oncology.

Technical Specifications
  • Dose Operating Range: 5 mRad to 1500 rad (50 μGY to 1500 cGy) for general applications; linear response up to 300 rad (cGy) for medical dosimetry, with software-supported non-linear calibration up to 1500 rad (cGy).
  • Lower Limit of Detection (LLD): 5 mrad (50μGy).
  • Useful Energy Range: 5 keV to 20 MeV.
  • Energy Dependence: Accurate within ±10% over diagnostic energy range 70-140 kvP; within ±5% for photons and electrons from 5 MeV-20MeV.
  • Accuracy: ±10% with standard nanoDot; ±5.5% with screened nanoDot.

Features and Benefits
  • Wide operating energy range makes nanoDots suitable for various settings, including diagnostic radiology and radiation oncology.
  • Non-destructive readout allows for reanalysis and electronic data archiving.
  • No post-measurement correction factors required.
  • 2D bar code includes dosimeter sensitivity and serial number for chain of custody.
  • Single-use dosimeters eliminate the need for preparation, such as heating or nitrogen gas.
  • Minimal angular or energy dependencies with appropriate calibration.
  • Can be used for skin dose measurements, on curved surfaces, and for in- and out-of-field measurements.
  • Wireless and radiolucent, can be placed anywhere on the body.
  • Can be used without buildup for surface dose measurements or with buildup for measurements at various depths.

Additional Information
LANDAUER provides calibration dosimeters for different applications, and nanoDots are shipped ready for clinical use. For further inquiries, contact LANDAUER or CIRS.

nanoDot™ Dosimeter-1

This is a nanoDot with alphanumeric sensitivity code and serial number (DN091=0.91 sensitivity). Either the front or back of the carrier can face toward the radiation source during exposure nanoDot™ Dosimeter Patient Monitoring Solutions NanoDot dosimeters are designed for use in single point radiation assessment applications and are engineered to be read by the microSTAR®ii reader. The nanoDot offers complete reanalysis, requires no dosimeter preparation in the clinic and has a labeled sensitivity that is built into the dosimeter 2D bar code for rapid, accurate reading. Overview Regulatory authorities and experts agree that reducing radiation errors in medical imaging and radiation oncology is a priority, but there is little guidance on practical strategies. LANDAUER’s optically stimulated luminesence (OSL) technology, featuring nanoDot dosimeters and microSTARii readers, provides one universal, simple and flexible solution to this complex problem. Since 1998, OSL technology has been trusted to measure occupational radiation dose for millions of health care professionals across the globe. OSL dosimeters are used for occupational dose monitoring in more than 80% of hospitals in the United States and are the subject of more than 30 published, peer-reviewed scientific publications. LANDAUER’s nanoDot OSL-based medical dosimeter is an effective tool to independently verify the quantity of dose delivered from radiation producing devices in medical imaging and radiation oncology. It provides an inexpensive insurance policy to mitigate litigation risk for your facility. Technical specifications above reflect minimum expected performance when the microSTARii reader is operated in compliance with all LANDAUER recommended reader performance quality assurance protocols. Note: The data provided by this product is informational and for quality assurance control purpose. The output of the microSTARii is not used to adjust the dose to the patient.
