Polonium ist ein radioaktives chemisches Element mit dem Elementsymbol Po und der Ordnungszahl 84. Im Periodensystem steht es in der 6. Hauptgruppe, bzw. der 16. IUPAC-Gruppe, wird also den Chalkogenen zugeordnet.
How did Marie Curie discover polonium?
Polonium was discovered by Marie Sklodowska Curie, a Polish chemist, in 1898. She obtained polonium from pitchblende, a material that contains uranium, after noticing that unrefined pitchblende was more radioactive than the uranium that was separated from it. ... Bismuth-210 decays into polonium-210 through beta decay.
Who discovered polonium in 1898?
In 1898, the Curies discovered the existence of the elements radium and polonium in their research of pitchblende. One year after isolating radium, they would share the 1903 Nobel Prize in physics with French scientist A. Henri Becquerel for their groundbreaking investigations of radioactivity.
When was radium and polonium discovered?
The topic was moribund when Marie Curie entered the scene. However, within eight months in 1898 she discovered two elements, polonium and radium, founding a new scientific field—radioactivity.
Why did they lick radium?
The factory manufactured glow-in-the-dark watch dials that used radium to make them luminous. The women would dip their brushes into radium, lick the tip of the brushes to give them a precise point, and paint the numbers onto the dial. That direct contact and exposure led to many women dying from radium poisoning.

How is polonium used today?
Polonium is an alpha-emitter, and is used as an alpha-particle source in the form of a thin film on a stainless steel disc. These are used in antistatic devices and for research purposes. A single gram of polonium will reach a temperature of 500°C as a result of the alpha radiation emitted.
Can polonium kill you?
Polonium was named after Marie Curie's homeland of Poland. Polonium has few applications, and those are related to its radioactivity: heaters in space probes, antistatic devices, sources of neutrons and alpha particles, and poison. It is extremely dangerous to humans.
What is the most radioactive thing on earth?

- Plutonium 239: 24,300 years.
- Plutonium 238: 87.7 years.
- Cesium 137: 30.2 years.
- Strontium-90: 28-years.
What is the most dangerous element?
Plutonium A History of the World's Most Dangerous Element.
How does polonium kill you?
If polonium-210 enters the body, through inhalation, swallowing, broken skin, the results can be fatal. By mass, polonium-210 is one of the deadliest toxins, around 250 billion times more toxic than hydrogen cyanide.
Can you buy polonium?
Yes, Polonium-210, "which experts say is many times more deadly than cyanide," the story notes, "can be bought legally through United Nuclear Scientific Supplies, a mail-order company that sells through the Web.
Is polonium man made?
Polonium is a radioactive element that occurs naturally in tiny amounts (which are harmless to us). ... Although polonium-210 was first isolated from uranium ores, today it can be artificially made by bombarding atoms of the metal bismuth with neutrons.
Is Chernobyl still burning?
The 2020 Chernobyl Exclusion Zone wildfires were a series of wildfires that began burning inside Ukraine's Chernobyl Exclusion Zone in April 2020. The fires were largely extinguished within two weeks.
Was Fukushima worse than Chernobyl?
Chernobyl had a higher death toll than Fukushima
Within three months of the disaster, more than 30 people had died of acute radiation sickness. ... While Chernobyl's radiation spread throughout Europe, much of Fukushima's radiation was released into the Pacific Ocean.
Is Fukushima still leaking nuclear waste?
The accumulating water has been stored in tanks at the Fukushima Daiichi plant since 2011, when a massive earthquake and tsunami damaged its reactors and their cooling water became contaminated and began leaking. ... TEPCO says its water storage capacity of 1.37 million tons will be full around the fall of 2022.
Is there a cure for polonium poisoning?
The alpha particles emitted from the decaying substance get absorbed in the body, which is what causes harm. Death may come in a matter of days, sometimes weeks. There is no cure for severe radiation poisoning, Dallas said.
Is polonium used in nuclear bombs?
There are 33 known isotopes (atoms of the same element with a different number of neutrons) of polonium, and all are radioactive. This element's radioactive instability is what makes it a fitting candidate for use in atomic bombs.
Is there an antidote for polonium?
Even if doctors discovered the poison sooner, polonium-210 has no antidote. Litvinenko died three agonizing weeks later. As the polonium-210 underwent alpha decay, it was a race against the clock to solve Litvinenko's murder.
What are 3 uses for polonium?
[2] By taking advantage of its high radioactivity, Po-210 has been used in three predominant applications: as a static eliminator, as a heat/energy source, and as a neutron source when combined with a low atomic weight element.
