Astatine is a radioactive, natural element and also a nonmetal similar to halogens.
None of these options are correct. The radioactive nonmetal element is polonium (Po). It is a highly toxic and rare element that undergoes radioactive decay.
Polonium applications: - Source of neutrons: as Po-BeO - Radioisotope thermoelectric energy source - Alpha particles source - Brushes with Po to eliminate static charges from different surfaces - Material in radiochemistry studiesRadium is used as radioactive source to treat some cancers, in industrial radiography, in Ra-Be neutron sources..

Radium (Ra)
You think probably to radium (Ra) and polonium (Po).
The decay chain of Th-232 contain Rn, Ra, Ac, Po, Bi, Po, Tl; the last isotope in the series is Pb-208 - stable.
Ra is the chemical symbol for Radium - a highly-radioactive element.

Studying RA 9165, or the Comprehensive Dangerous Drugs Act of 2002, is important because it provides critical information on drug offenses, penalties, and procedures for handling dangerous drugs. Understanding this law is essential for professionals in law enforcement, healthcare, and social services to effectively combat drug abuse and trafficking in the Philippines.
Radium (Ra)
Radium is an alkaline earth metal, group 2, period 7; Ra is a radioactive.
Polonium (Po) and radium (Ra) are two different chemical elements.
