CoGeNT: A Search for Low-Mass Dark Matter using p-type Point Contact Germanium Detectors

, 2013
CoGeNT employs p-type point-contact (PPC) germanium detectors to search for Weakly Interacting Massive Particles (WIMPs). By virtue of its low energy threshold and ability to reject surface backgrounds, this type of device allows an emphasis on low-mass ...

Radon Daughter Plate-out onto Teflon

, 2017
Radiopure materials for detector components in rare event searches may be contaminated after manufacturing with long-lived $^{210}$Pb produced by the decay of atmospheric radon. Charged radon daughters deposited on the surface or implanted in the bulk of

Joint and Rapid Determination of 210Pb-210Bi-210Po in Rock, Soil and Sediment Samples by Constant Temperature Spontaneous Deposition on Cu-foil with Gross α and Gross β Counting

Yankuang ceshi, 2013
Measurement techniques of uranium series nuclides 210Pb, 210Bi and 210Po are relatively independent at present for most cases, and there are still some technical issues that need to be overcome.

Development of a Li2MoO4 scintillating bolometer for low background physics

, 2013
We present the performance of a 33 g Li2MoO4 crystal working as a scintillating bolometer. The crystal was tested for more than 400 h in a dilution refrigerator installed in the underground laboratory of Laboratori Nazionali del Gran Sasso (Italy).

The Radiological Impact of 210Pb and 210Po Released from the Iron- and Steel-Making Plant ILVA in Taranto (Italy) on the Environment and the Public

Journal of Chemistry, 2013
Lead-210 and 210Po are naturally occurring radionuclides. Due to volatile characteristic of lead and polonium, environmental pollution of 210Pb and 210Po released from the coal power plant, steel-making industry and refractory material industry has been ...

Quantitative assessment of the radon (222Rn) decay product 210Pb in human toenails as a sensitive measure of personalized long-term radon gas exposure history

Environment International
Lung cancer mortality can be lowered through early-diagnostic screening of people demonstrating a ≥1.5 % 6-year risk of tumor development. However, many who develop lung cancer are ineligible for screening (∼40 % of Canadian patients) as they have ...

High-resolution decadal-scale eruption age dating of young oceanic basalts at an active hydrothermal vent site

Frontiers in Geochemistry
Here we report (210Pb/226Ra), (226Ra/230Th), (230Th/238U) and (234U/238U) disequilibria for eleven lavas from the ABE vent site in the Lau Basin. Most ABE lavas have (210Pb/226Ra) > 1 and (226Ra/230Th) > 3. These results indicate that most of these
