Dosimetry Services

SG&A recognise that monitoring programs often require multiple badge types and monitoring periods and we offer a wide array of dosimeters from the traditional thermoluminescent (TLD), to the revolutionary Instadose™ dosimeters. Transforming the way facilities manage their radiation monitoring programs, instadose dosimeters help increase compliance and lower radiation exposure risk for employees. From dose reads captured by smart phones, tablets, or internet enabled computers to on-demand dose data and online reports, we help you save time, pinpoint exposures and mitigate exposure risks with ease

With real-time reporting and tracking capabilities it allows users to pinpoint high dose exposures and anomalies faster because only Instadose™ dosimeters enable on-demand and scheduled calendar reads with online access to both historical and current dose measurements and reports.


Benefits of the instadose+

The Instadose+™ badge will be set to upload monthly, automatically, at any location that has any of the above active communication devices.

If you ever miss the upload day, or you have a query about your dose and want to check whether a dose has been received, an additional manual upload can be done at any time.

Instadose+™ badges are available in a variety of colours and can be kept for many years (for as long as the battery lasts), at which time they will be replaced by Mirion, making them very cost effective.

How do they work?

Instadose+™ dosimeters use Bluetooth Low Energy (BLE) Technology to transmit dose data. The following communication devices are used to capture reads from instadose+ badges that are within range:

• Smart devices with BLE technology with the instadose app installed

• PCs with an instaLink-USB connected

• instaLink Hotspot Stations




MeasuRing & Fingertip Dosimeters

Rings and fingertip dosimeters are ideal for low or high energy beta, X-ray or gamma radiation monitoring of hands and fingers.

Our MeasuRing is bar coded and consists of one powdered lithium fluoride element in a single-piece construction. The MeasuRing can be immersed and cold sterilised.

Fingertip dosimeters also consist of one powdered lithium fluoride element which is sealed in a plastic pouch and placed in a finger cot that can be placed directly over the finger

Fingertip dosimeters are designed for individuals handling radioisotopes, performing interventional radiographic procedures, or who have a higher risk of radiation exposure to their hands and fingers.





  • Ideal for individuals who have a higher risk of exposure to their hands and fingers
  • Wear periods from one week to six months
  • Can be worn under surgical gloves
  • Perfect to measure extremity dose
  • Individually calibrated.
  • Available in 4 sizes.
  • Can be immersed in water and cold sterilized 




Eye Dosimetry 

Eye dosimeters provide accurate readings for radiation received to the vicinity of the eye. All eye dosimeters consist of one natural lithium fluoride element sealed in a plastic holder that mimics the density of the eye.

When worn with the head strap near the eye, the dose received by the element can be easily correlated to the eye dose. Each eye dose dosimeter is uniquely barcoded and labelled for ease in identification and chain of custody

Designed for individuals who have higher risk of radiation exposure to localised sources eg. cath lab, fluoroscopy etc.






  • Adjustable head strap
  • Can be cold sterilised 
  • Wear periods of one week to one quarter. 





The Genesis Ultra TLD responds accurately to beta, gamma, X-ray, and neutron radiation. 

Unlike other TLD products, the Genesis Ultra TLD has virtually no fading characteristics. Due to the increase in signal response a minimum reportable dose (MRD) as low as 1 mrem (0.01 mSv) is available, compared to the 10 mrem (0.10 mSv) MRD of other TLD products.
