radon

Colorless, odorless gas that occurs naturally due to the breakdown of minerals in the earth. It tends to become trapped in our modern, nearly air-tight homes. Since there has been some correlation between radon and lung cancer, the EPA recommends levels no higher than 4 picocuries per liter (pCi/L), although generally acceptable levels are in the range of 4 to 8 pCi/L. The EPA Web site at www.epa.gov has information on testing for radon and reducing it.

The Niton XLT 797X analyzer is available for on-site demonstration beginning September 2006 and is available for mid-October 2006 delivery.
Paired t-tests were used to evaluate whether the Niton readings differed significantly from the laboratory results.
The portable XLt can also be used anywhere it, Niton says, including on the assembly line, in the warehouse, on the back of a truck or on supplier trips around the globe.
This result is encouraging, and surface exploration of the Hibernia-Wynd's trend will continue in an attempt to identify the most prospective zone along its 30km strike length.Tantalum, Tin, Nickel, CopperEuriowie - (Carpentaria owns rights to 100% of base and precious metals other than lithium) - Reconnaissance Niton results highlight two areas with elevated tantalum, tin, nickel and copper results.EL 6936 is centred approximately 60 km to the north of Broken Hill and contains Paleo-Proterozoic Paragon and Sundown Group metasediments prospective for Broken Hill and Century/Mt Isa style base metal deposits.
JANINE TOPMAN and Joseph Richardson, of Niton Road, Weddington, Nuneaton, married at Nuneaton Register Office and held a reception at The Chase Hotel, Nuneaton.
What's said to be the first hand-held x-ray fluorescence (XRF) analyzer for plastics is newly available from Niton LLC, Billerica, Mass.
In 2003, NITON, which has a market-leading position for handheld XRF instruments, began shipping the Xli, an ergonomic isotope-based XRF that weighs a scant 1.7 lb, and the XLt, a sleek x-ray tube analyzer.
In addition to offering x-ray tube systems, Niton offers an isotope-based system featuring the Infiniton isotope that is maintenance free, never needs replacement and never slows down as do the traditional cadmium 109 isotopes.
The Meknes zone style corresponds to a brittle-ductile shear zone replaced by intense pervasive silica tourmaline alteration.The visible cassiterite is associated with millimetre to centimetre scale quartz veins and spot analysis with the NITON hand held XRF indicates these veins run from 1% to 3% tin, consistent with this style of mineralisation intersected by previous drilling in the Meknes zone.The second style of mineralisation is similar to that seen in the Eastern zone of the Achmmach hill, where tin (1-2%) is associated with pyrrhotite veins.
So mum Susan, 37, and dad Ryan, 40, moved to Niton, on the southern tip of the Isle of Wight - which has just one street lamp.
