  • Boulby isa working potash minein the North East of England. Operated by Cleveland Potash Ltd – a major local employer.

  • 1100 m deep(2805 m w.e.).

U:67 ± 6 ppb

Th:125 ± 10 ppb

K:1130 ± 200 ppm

Rn:2.5 ± 1.6 Bq m-3


Low background counting

Low-background counting

Ultra-low background Ge detector for gamma spectrometry & material selection.

Low background, high sensitivity, 2kg (~400cc) Ge detector for material activity measurements.

Sensitivity of ~1-10ppb U/Th for typical samples.

Aim now to upgrade facilities giving x100 increase in sensitivity

Radon emanation measurement

Based on a high sensitivity, low background commercial Rn detector (Durridge Rad7). Sensitivity <0.02 Bq/sample.

Gd loaded scintillator used for n measurement:

Flux = (1.72±0.61(stat.)±0.38(syst.))·10-6 cm-2s-1

Horizontal access

Science projects (bb of 116Cd, R&D for SuperNEMO and radiopure crystals)

  • Salt domes

  • a lot of space!

  • shallower depth ~208 m from the surface(600 m.w.e.)

  • used for low background radiation measurements (too shallow for most astroparticle physics experiments)


Conclusions

Conclusions

  • Many underground sites available for science in Europe with depth > 1 km w.e.

  • Four main deep-underground Labs (LNGS, LSC, LSM, Boulby) very well established, with a rich physics program (dark matter, neutrinos, double beta decay)

    • closer coordination and interchanges started in the framework of EU-funded programs (ILIAS)

    • memorandum of understanding (EULabs)

  • Baksan Lab still operational (SAGE) in spite of difficulties

  • Other “emerging” sites becoming available, expecially in Eastern Europe

    • infrastructures for full-scale science experiments not yet available

    • presently tests, background characterization, measurements with HPGe
