A National Nuclear Forensic Library (NNFL) is a useful nuclear forensics tool which consists of information and subject matter expertise on radioactive and nuclear (RN) materials produced, used or stored within a State. If RN material is found out of

A two-parameter modeling formula is proposed for quadrupole ICP-MS (ICP-QMS) data, which corrects for nonlinearity with a “dead-time” function and makes subsequent weighted mass-bias corrections to normalize isotope ratio data to pertinent isotop

A plutonium alpha standard dating from 1948 was discovered at Argonne National Laboratory and characterized using a number of non-destructive analytical techniques. The principle radioactive isotope was found to be 239Pu and unique ring structures we

Age-dating of 137Cs ceramic sources is shown to be a viable technology for nuclear forensics investigations. The 137Cs age-dating method in general, however, could be substantially improved by using radiometric rather than ICP-MS measurement of the 1

X-ray fluorescence (XRF) is an attractive technique for nuclear forensics applications. We evaluated a handheld XRF device by applying an external radiation field (10 mR/h–17 R/h) using two types of radiography sources: a 60Co radiography camera fo

Ecological responses to environmental change are wide-ranging, from alterations in the timing of life-history events to range and population changes. Explaining the variation across species in these responses is essential for identifying vulnerable s

A revision of Rhododendron subgenus Tsutsusi is presented: section Tsutsusi with 66 species is equivalent to series Azalea subser. Obtusum; and section Brachycalyx with 15 species includes some species previously placed in subser Schlippenbachii. One
