This is called background radiation and it varies across the country. The average American is exposed to about 3 mSv (millisieverts) of radiation from natural sources over the course of a year. (A ...

Nanocrystalline (NC) semiconductor materials have previously been studied as a means of increasing the exciton multiplicity upon the impingement of visible light, for applications such as solar cells.

Officials said they are investigating the presence of a type of “radioactive material” found in a science lab.

A compound semiconductor, thallium bromide (TlBr), has been investigated as an optical and radiation detector material for use in X- and /spl gamma/-ray spectroscopy. Single crystals of TlBr have been ...

Marie Curie worked with radioactive material with her bare hands. More than 100 years later, Sophie Hardach travels to Paris to trace the radioactive fingerprints she left behind.

Upcycling Plastic Waste into Durable Materials. Radiation isn’t just for creating new materials — it’s also being used to upgrade or “upcycle” existing plastic waste into more valuable, durable forms.

A documented survey (using this form) is required at least once every month radioactive materials are used. The Survey Report is due at Environment, Health & Safety on the first day of the month to ...

Metal halides have excellent radioluminescence performance, which makes them suitable for X-ray indirect flat panel detectors (I-FPDs). However, commercialization prospects are still constrained by ...

The cumulative absorbed radiation doses of tumor tissue are at least 42-fold higher than that of peritumoral liver tissue, which is attributed to specific tumor targeting and prolonged retention of ...
