Hair radioactivity as a measure of exposure to radioisotopes [PDF]

, 1972
Since many radioisotopes accumulate in hair, this tropism was investigated by comparing the radioactivity of shaved with plucked hair collected from rats at various time intervals up to 24 hrs after intravenous injection of the ecologically important ...

A Radio Science Experiment for Dragonfly to Investigate Titan's Rotation and Interior Structure

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract NASA's mission Dragonfly to Titan is scheduled for launch in 2028 with arrival in 2034 to study Titan's prebiotic chemistry and habitability. We propose a radio science experiment for Dragonfly, in which radiometric tracking of the rotorcraft from the Deep Space Network, already baselined for communications and navigation, is used as a ...

Study of secondary implantation of radioisotopes during alpha-particle irradiation

, 2019
This work presents the recoil and secondary implantation of radioisotopes at different bombarding energies in the range of ~ 13 to ~ 40 MeV by using an α-particle beam of 50 MeV irradiating a stack of Ag, Ni and Ti metal foils.

Future Supply of Medical Radioisotopes for the UK Report 2014

, 2015
The UK has no research nuclear reactors and relies on the importation of 99Mo and other medical radioisotopes (e.g. Iodine-131) from overseas (excluding PET radioisotopes). The UK is therefore vulnerable not only to global shortages, but to problems with

Medicinal Applications of Radioisotopes

, 2019
In the medical field, radioisotopes are used for two distinct functions: diagnosis and therapy. The four main diagnostic radioisotopes are technietium-99m, thallium-201, iodine-123, and gallium-67, which are used to figure out which areas of the body ...

Cosmogenic 10Be as a Tracer for Recent Heliospheric Encounters With Interstellar Cold Clouds and Nearby Supernovae

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract Recent works suggest there are periods when the Sun encountered massive interstellar cold clouds which compressed the heliosphere to within Earth's orbit, exposing Earth to interstellar galactic cosmic rays and energetic particles of heliospheric origin.

A Qualitative Review of Clinical Decision‐Making Using [99mTc]Tc‐Mercaptoacetyltriglycine Renal Scintigraphy in Patients With Malignant Ureteral Obstruction

Journal of Medical Radiation Sciences
Introduction Urinary drainage (ureteral stenting or percutaneous nephrostomy) is commonly used for malignant ureteral obstruction (MUO), but optimal indications remain unclear. [99mTc]Tc‐mercaptoacetyltriglycine (MAG3) renal scintigraphy assesses urinary

Studies with Colloids Containing Radioisotopes of Yttrium, Zirconium, Columbium, and Lanthanum: 1. The Chemical Principles and Methods Involved in Preparation of Colloids of Yttrium, Zirconium, Columbium, and Lanthanum

, 1948
For a number of investigations, including fundamental studies of radiation effects on living tissues and therapeutic utilization of radioisotopes, it is valuable to have methods for the selective localization of radioisotopes in certain tissues.

Production scheme for diagnostic-therapeutic radioisotopes by accelerator neutrons

Interest has been growing in the development of medical radioisotopes used for noninvasive nuclear medicine imaging of disease and cancer therapy. Especially the development of an alternative production scheme of 99Mo, the mother radioisotope of 99mTc ...
