Establishment of a Purge and Trap Continuous-Flow Isotope Ratio Mass Spectrometer System for Analysis of Stable Nitrate Isotopes (δ<sup>15</sup>N and δ<sup>18</sup>O) in Water Samples by Ti(III) Reduction. [PDF]
Rapid Commun Mass SpectromABSTRACT Rationale Pollution of surface and shallow groundwater by nitrate (NO3−$$ {\mathrm{NO}}_3^{-} $$) is a global concern, resulting in the deterioration of drinking water quality. Stable isotopes of NO3−$$ {\mathrm{NO}}_3^{-} $$ (δ15N and δ18O) can be used to trace its sources and identify prevailing biogeochemical processes.

Geophysical Monograph Series, Page 487-501., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Evaluation of internal exposure of nuclear medicine staff working with radioiodine in Poland
International Journal of Occupational Medicine and Environmental Health, 2023 The iodine-131 (I-131) content in the thyroid of staff members working with this radionuclides has been measured with about 500 employees in about 25 hospital’s departments of nuclear medicine performing therapy and diagnosis of thyroid disease in Poland.

Spins of Some Radioactive Iodine Isotopes [PDF]
Physical Review, 1958 The spins of I/sup 123/, I/sup 124/, and I/sup 131/ were measured by the method of atomic beams; the spins are 5/2, 2. and 7/2. respectively. The result I = 7/2 for I/sup 131/ confirms an earlier measurement by a different method. (auth)

Neutron Deficient Isotopes of Iodine [PDF]
Physical Review, 1950 Abstract : The iodine isotopes I(123), I(122), I(121), and I(120) (?) have been made by bombarding antimony with alpha-particles. Their characteristics are summarized and evidence for mass assignments presented. During the course of some investigations of abnormal change in nuclear charge following irradiation with high-energy particles, some of the ...

Radiation Dosimetry of Theragnostic Pairs for Isotopes of Iodine in IAZA
Pharmaceutics, 2022 Theragnostic pairs of isotopes are used to infer radiation dosimetry for a therapeutic radiopharmaceutical from a diagnostic imaging study with the same tracer molecule labelled with an isotope better suited for the imaging task. We describe the transfer

Dark antiatoms can explain DAMA [PDF]
, 2014 We show that the existence of a sub-dominant form of dark matter, made of dark antiatoms of mass and size of the order of 1 TeV and 30 fm respectively, can explain the results of direct detection experiments, with a positive signal in DAMA/NaI and DAMA ...
