Astatine is a chemical element; it has symbol At and atomic number 85. It is the rarest naturally occurring element in the Earth's crust, occurring only as the decay product of various heavier elements. All of astatine's isotopes are short-lived; the most stable is …

The following table shows the atomic nuclei that are isotonic (same neutron number N = 125) and isobaric (same nucleon number A = 210) with Astatine-210. Naturally occurring isotopes are …

The most stable isotope of astatine is astatine-210, which has a half-life of about 8.1 hours. This isotope's primary decay mode is positron emission to the relatively long-lived alpha emitter, polonium-210. In total, only five isotopes of astatine have half-lives exceeding one hour: those between 207 and 211.

This 8.1-hour half-life isotope exhibits characteristics that are not compatible with pharmaceutical applications because of its decay into the long half-life 210 Po (138.2 days), which is highly toxic, especially to the bone marrow. 10 Production of 210 Po is …

2018年9月1日 · We proposed use of astatine-210 in preclinical study. Astatine-210 has higher yield of production and is easier to quantify than astatine-211. We produced astatine-210 with Bi target and 40 MeV alpha beam accelerated by cyclotron, free astatine-210 was separated and injected to normal rats.

CLASSIFICATION Isotope: At-210 Atomic number (Z): 85 Mass number (A): 210 Neutron number (N): 125

Astatine's most stable isotope, astatine-210, has a half-life of 8.1 hours. It decays into bismuth-206 through alpha decay or into polonium-210 through electron capture.
