Determination of Natural Radioactivity in Iron and Steel Materials

, 2019
It has been known since the 1990s that two natural radioisotopes from the uranium-238 (238U) decay series, polonium-210 (210Po) and lead-210 (210Pb), originally present in trace amounts in raw materials, are volatilised and concentrate in the form of ...

Methods to measure iron absorption in humans: A review

, 1997
This paper reviews different methods for measuring iron absorption by using stable or radioisotopes. Methods using stable isotopes are of special interest because of the absence of radioactive exposure.

Discovering Shared Design Heritage for Semiconductor‐Based Gamma‐Ray Spectrometers: From CdTe to Metal Halide Perovskites

Laser &Photonics Reviews, EarlyView.
Decades of CdTe and CdZnTe gamma‐ray spectrometer development define core design principles for room‐temperature semiconductor detectors. This Review highlights how metal halide perovskites rapidly assimilate these principles, particularly through defect and compositional engineering strategies that establish favorable spectroscopic conditions for ...

2D van der Waals System Integrated with Targeting Radio‐Diagnostic and Imaging Functions

Small, EarlyView.
Layered double hydroxide (LDH) nanoplates were engineered for tumor‐targeted imaging and therapy. By exploiting folate receptor (FR) expression levels, the system achieves selective tumor accumulation and high‐resolution dual PET/fluorescence (PET/FL) imaging.

A Low‐Power Radioisotope XRF Spectrometer for Detection of Light Elements on Planetary Missions

X-Ray Spectrometry, EarlyView.
ABSTRACT Current X‐ray spectrometers for in situ geochemical analysis on planetary missions typically rely either on X‐ray tubes, which demand electrical power and add mass and thermal complexity, or on alpha particle X‐ray spectrometers (APXS) that use rare 244Cm$$ {}^{244}\mathrm{Cm} $$ sources, and come with severe concerns on radiation safety and ...
