The nanoDot® dosimeter is for use in single point radiation assessments. The nanoDot dosimeter measures radiation exposure with Optically Stimulated Luminescence (OSL) technology. This dosimeter is designed to be read out using a microStar® reader.
Each nanoDot is a chip of OSL material with a diameter of 4 mm. It is enclosed in a light-tight carrier, and is shipped enclosed in a plastic packet that protects against contamination. Carriers have unique serial numbers for identification and tracking.

The nanoDot is designed for the client with extensive data management capabilities who prefers to independently maintain data and issue exposure reports. This compact dosimeter can be used in awkward to access places. The plastic packet enables it to be sterilised without compromising the integrity of the dosimeter.
With a microStar reader, the nanoDot gives an immediate measurement of the dose. For reading, the dosimeter is pulled out from its plastic pouch and clipped in a carrier. microStar permits an in situ analysis.

The TLD chips use a Lithium Fluoride (LiF) chip with no binder as the detector. It is enclosed in a plastic pouch that protects against contamination. Chips are identified by a serial number written on a paper enclosed on the plastic pouch.
This compact dosimeter could be used in difficult access places. The plastic pouch enables the TLD chips to be sterilised without compromising the integrity of the dosimeter.
For instantaneous reading, we recommend the use of our portable reader microStar and nanoDots (OSL chips).
