Characterization and calibration of the iQID digital autoradiography system for direct quantitative imaging of beta‐emitters in tissue samples

Medical Physics, Volume 53, Issue 8, August 2026.
Abstract Background Autoradiography provides microscale mapping of radionuclide distributions, offering a promising approach to complement nuclear medicine imaging for small‐scale radiopharmaceutical therapy (RPT) research. However, while quantitative protocols for α‐emitters are well‐established, comparable methods for β‐emitters, such as the widely ...

Photon minibeam‐based LATTICE radiotherapy for small and medium‐sized tumors: A dosimetric planning study

Medical Physics, Volume 53, Issue 8, August 2026.
Abstract Background Lattice radiotherapy (LRT) is a spatially fractionated technique that delivers three‐dimensional high‐dose vertices within tumors. However, conventional LRT is constrained by geometric limitations when applied to small and medium‐sized tumor volumes, primarily due to the large beam sizes that restrict optimal lattice pattern ...

Assessment of Spacecraft Internal Charging in the Earth's Outer Radiation Belt

Space Weather, Volume 24, Issue 8, August 2026.
Abstract The internal charging effects triggered by energetic (>100 keV) electrons in the Earth's radiation belts can cause anomalies and failures of electronic components aboard spacecraft. Given the critical importance of safeguarding space assets, it is essential to estimate internal charging risks, which depend highly on the distribution of ...

Latitude Survey of Neutrons and Muons to Determine Cosmic Ray Neutron Sensing Yield Functions

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract Cosmic Ray Neutron Sensing (CRNS) is a ground‐based technique that utilizes epithermal neutron measurements as a proxy for environmental hydrogen content. Similarly to other ground‐based cosmic ray detectors (e.g., neutron monitors), CRNS detectors are affected by the solar cycle and space weather events.

Terrestrial Gamma‐Ray Flash Following Intense Negative Return Stroke Observed With BIMAP‐3D

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 13, 16 July 2026.
Abstract We report ground‐based observations of a terrestrial gamma‐ray flash (TGF) associated with a strong negative cloud‐to‐ground lightning strike (‐CG) which occurred near Los Alamos National Laboratory (LANL) in New Mexico, USA. Gamma photons were detected by the Terrestrial High‐energy Observations of Radiation (THOR) instrument, developed at ...

Research and Development of a Natural Radioactivity Detection System for Import and Export Goods

Journal of Isotopes
China imports a large amount of bulk minerals and rare metals every year，and during customs radiation monitoring，harmless alarms are often triggered due to the presence of natural radioactive elements (NORM) in the minerals.

Real‐time motion tracking of a gold implant in water by Cherenkov lights

Journal of Applied Clinical Medical Physics, Volume 27, Issue 7, July 2026.
Abstract Background The intra‐fraction motion of tumors during radiation therapy can be monitored using imaging systems based on X‐ray imaging (e.g., kV/MV radiography or CBCT) or magnetic resonance imaging (MRI). However, these techniques have limitations, including additional ionizing radiation dose and the need for complex, expensive equipment ...

Biomimetic Polymerization of Tellurocysteine: Breaking the Natural Amino Acid Radioprotection Limitation

Advanced Science, Volume 13, Issue 37, 3 July 2026.
Inspired by natural amino acid polymer‐melanin systems, this study strategically incorporated tellurocysteine to develop advanced radiation‐shielding materials. This approach transformed the primary interaction mechanism between melanin‐based materials and incident photons from Compton scattering to the photoelectric effect. Tellurocysteine‐polymerized
