What is gadolinium-153 used for?
Because of its magnetic properties, Gadolinium-153 (Gd-153) is used in intravenous radiocontrast agents in magnetic resonance imaging (MRI). JSC Isotope is ready to supply you with Gd-153.
How long does it take for half the amount of gadolinium-153 to decay?
Gadolinium-153 is an intermediate-energy isotope that emits 40-100 keV photons with a half-life of 242 days.
How many isotopes does Gd have?
6
Naturally occurring gadolinium (64Gd) is composed of 6 stable isotopes, 154Gd, 155Gd, 156Gd, 157Gd, 158Gd and 160Gd, and 1 radioisotope, 152Gd, with 158Gd being the most abundant (24.84% natural abundance).
Who discovered GD 153?
These were caused by the element we now know as gadolinium. In 1886, French chemist Paul Émile Lecoq de Boisbaudran confirmed Marignac’s discovery. Boisbaudran suggested the name gadolinium for the new element after the 18th century chemist and mineralogist Johan Gadolin. The name was accepted by Marignac.
What is gadolinium used in?
Gadolinium-Based Contrast Agents (GBCA) are intravenous drugs used in diagnostic imaging procedures to enhance the quality of magnetic resonance imaging (MRI) or magnetic resonance angiography (MRA).

Is neptunium 237 radioactive?
… are radioactive; the stablest is neptunium-237, with a half-life of 2,144,000 years, and among the most unstable is neptunium-225, with a half-life of more than 2 microseconds. Neptunium-237 can be separated from used reactor fuel to study the physical and chemical properties of the element.
What is the 65th element?
Terbium, element number 65, is no different and lies in the middle of the lanthanide series in between gadolinium and dysprosium. It is one of the rarer rare earth elements, although it is still twice as common as silver in the Earth’s crust.

What was samarium named after?
mineral samarskite
The mineral samarskite, from which samarium was first isolated, is named after Colonel Samarsky, a Russian mine official. The Soviet hammer, sickle and star are on a background that reflects the use of the element in lasers. A silvery-white metal. Samarium-cobalt magnets are much more powerful than iron magnets.

What does gadolinium do to the brain?
Gadolinium enhances the quality of MRI by altering the magnetic properties of water molecules that are nearby in the body. Gadolinium can improve the visibility of specific organs, blood vessels, or tissues and is used to detect and characterize disruptions in normal physiology.
