Low Background Counting Low background counting is a critical component of low event rate experiments in nuclear and astroparticle physics. These experiments often require materials with a high degree of radiopurity to avoid excessive background signals in their region of interest. Passive counting using a low background HPGe detector is often performed to screen candidate construction materials for primordial radioisotopes (U, Th, K), common man-made products (Cobalt-60, Cesium-137, etc.), or even cosmogenic activation products. Neutron Activation Analysis and Monitor Measurements We perform regular counting of materials (both monitor foils or samples) activated by neutrons or particle reactions for determining trace element concentrations via neutron activation analysis, neutron beam flux measurements, and more. ICPMS (via Earth Science Division) We have an affiliation with the ICPMS services located in the Earth Science Division, which is an alternative for gamma screening and sometimes a useful comparison to do both. Environmental Monitoring Regular monitoring of air using HEPA filters and automobile filters is conducted at LBNL. Additional samples of soils, sediments, biota, and miscellaneous environmental samples are conducted. Waste Assay We perform various assay services for legacy waste disposal and experiment decommissioning. |
