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.
Is gadolinium an isotope?
Naturally occurring gadolinium is composed of six stable isotopes, 154Gd, 155Gd, 156Gd, 157Gd, 158Gd and 160Gd, and one radioisotope, 152Gd, with the isotope 158Gd being the most abundant (24.8% natural abundance).
How many isotopes does gadolinium have?
six
In nature the element occurs as a mixture of six stable isotopes—gadolinium-158 (24.84 percent), gadolinium-160 (21.86 percent), gadolinium-156 (20.47 percent), gadolinium-157 (15.65 percent), gadolinium-155 (14.8 percent), and gadolinium-154 (2.18 percent)—and one radioactive isotope, gadolinium-152 (0.20 percent).
Who discovered GD 153?
Gadolinium Properties In its elemental form, CAS 7440-54-2, gadolinium has a silvery-white appearance. Gadolinium was discovered by Jean Charles Galissard de Marignac in 1880 and first isolated by Lecoq de Boisbaudran in 1886. The element is named after the Finnish chemist and geologist Johan Gadolin.
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).
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 is the half-life of cobalt 57?

What is gadolinium toxicity?
Toxicity is a side effect of GBCAs that can occur within hours after undergoing an MRI scan with one of these contrast agents. Or it can manifest years later in people who have gadolinium buildup in their bodies. Symptoms vary from person to person. The severity ranges from mild to severe.
What is gadolinium used for in everyday life?
It is also used in alloys for making magnets, electronic components and data storage disks. Its compounds are useful in magnetic resonance imaging (MRI), particularly in diagnosing cancerous tumours. Gadolinium is excellent at absorbing neutrons, and so is used in the core of nuclear reactors.
What is the symbol of terbium?

Which element is dy?
dysprosium
dysprosium (Dy), chemical element, a rare-earth metal of the lanthanide series of the periodic table. Dysprosium is a relatively hard metal and is silvery white in its pure form. It is quite stable in air, remaining shiny at room temperature.
