γBeaker and accompanying accessories

DESCRIPTION

The γBEAKER is a dedicated solution to the problem of radon emanation in gamma spectrometry.

In gamma spectrometry, the noble gas 222Rn needs to be kept inside measurement beakers when the concentrations of 238U decay chain members are measured via the 222Rn daughter products. 222Rn emanation and leakage may lead to an underestimation of 238U concentration.

Additional variability of results may arise when beakers (even of the same type) or sealings display varying 222Rn degrees of leakage. Read here

Advantages offered by the containers:

  • The γBEAKER line ensures nearlz full elimination of radon leakage and a retention of more than 98% of 222Rn emanating from sample
  • Custom made design allows matching any gamma detector or specific geometries for low level environmental radioisotopes measurement.
  • No mixing with wax/resin is needed to trap the radioactive gas. 
  • Made from very low radioactivity materials
  • Reusable and durable
  • Easily cleaned and maintained
  • Light-proof version available on demand


SYSTEM PRESENTATION


γSPIKE

γSPIKE is a non-invasive and non-destructible solution to self-absorption occurring within samples in gamma and X-ray spectrometry

To compensate for the bias introduced by self-absorption, a radioactive spike can be added and mixed with the sample. Unfortunately, this process makes it impossible to later recover the raw sample. γSPIKE, however, offers a solution where the radioactive spike is encased in small capsules and has no contact with the sample. Additionally, the capsules are distributed uniformly within the sample, which makes γSPIKE a great alternative to the typical solution.

Advantages of γSPIKE:

  • Allows for volumetric correction of low-energy lines in various samples, without the need for additional calculations
  • Provides non-destructive and non-invasive alternative to mixing samples with a radioactive spike
  • No need for adding radioactive spike to the sample
  • Custom-made for γBEAKERs of chosen sizes
  • Comes with a radiation-blocking mount
  • Made from very low-radioactivity materials
  • Reusable and durable
  • Easily maintained

γCOLLIMATOR

γCOLLIMATOR is a well-known collimating solution for countering the self-absorption issue, designed to match γBEAKERs of choice

One of the solutions to estimate self-absorption correction is to place a radioactive source right above the measured sample. The collimated γ beam passes through the sample and partially absorbed reaches the detector. This allows for determining appropriate correction factors for the low-energy isotopes (Bonczyk et al., 2016, Bonczyk, 2018).

Properties of the γCOLLIMATOR:

  • Radioactive material of choice is placed in the bottom part of the γCOLLIMATOR and secured tightly within the shielding
  • Radioactive material can be easily removed from the γCOLLIMATOR
  • Custom-made to fit γBEAKERs of chosen sizes perfectly
  • Comes with a radiation-blocking mount
  • Made from very low-radioactivity materials
  • Reusable and durable
  • Easily maintained
