Alanine Loose Pellet Dosimeters

What is an Alanine Loose Pellet Dosimeter?

Sold in containers of 1,000, Alanine Loose dosimeter Pellets are typically used as reference dosimeters to measure absorbed doses of ionizing radiation. A protective holder is needed for measurement within a spectrometer. In a controlled environment doses ranges of 0.1kGy to 100kGy can be measured using alanine pellets.

Alanine Loose Pellet Dosimeter Batch and Lot Naming

A batch of Alanine Loose Pellet dosimeters are characterized by letters. For example, ‘DX’ and is defined as the manufactured quantity prior to being split into weight groups. Once each batch is weight sorted, these groups of pellets are known as lots. Lots are grouped in weights of +/- 0.6mg, and are characterized numerically, for example ‘DX600’.

What is the Dose Range of Alanine Loose Pellet Dosimeters?

The functional dose range of Alanine Loose Pellet dosimeters is dependent on the measuring equipment and conditions used and are sold as being able to achieve a functional dose range of 0.1kGy to 70kGy. . When measured in a controlled environment, 0.1kGy to 100kGy can be achieved, making them ideal for most irradiation processes. Identification and measurement of the Alanine Loose Pellet dosimeter is completed using an electron paramagnetic resonance (EPR) spectrometer.

What is the Alanine Loose Pellet Dosimeter Measurement Reproducibility?

Irradiation response: CV up to 1.0%


  • Each loose pellet lot is verified via a third-party calibration
  • The shelf life of unirradiated dosimeters is eight years from date of release
  • All measurements on this specification are given at a coverage factor of K=2 (providing a coverage probability of approximately 95%)

What are the Alanine Loose Pellet Dosimeter Dimensions?

  • Diameter: 4.8mm +/- 0.1mm
  • Height: 2.8mm +/- 0.1mm
  • Batch Mass: Typically, 60mg +/- 2mg
  • Lot Mass: +/- 0.6mg within a lot
