What is astatine

Astatine is a highly unstable radioactive element, the heaviest of halogen series.

It’s the longest lived isotope has a mass number of 210 and a half-life of 8.3 hours

Astatine is like uranium but less unstable.

How it was created

In 1940 Doctor Corson discovered Astatine in The University of California with his friends Emilio Serge and K.R. Mackenzie

They created the Astatine by creating small amounts of Bismuth-209 with accelerated alpha particles.

Where you can find it

Astatine is found in uranium and thorium materials but in extremely low concentrations.

Uses for Astatine

Astatine is use for nuclear medicine like Cancer treatment.

Also Astatine is used for targeted alpha particles radiotherapy.

Since Astatine is like Iodine, it is also a treatment is also is use for thyroid treatment.
