Ang radyo (Iningles radium) mao ang elementong kimiko sa talaang peryodiko nga may simbolo nga Ra ug kaiphan nga atomik 88. Ang radyo mao ang puthaw.

Ang radium, sa porma sa radium chloride, nadiskubre ni Marie ug Pierre Curie niadtong 1898 gikan sa ore nga gimina sa Jáchymov.  Ilang gikuha ang radium compound gikan sa uraninite ug gipatik ang nadiskobrehan sa French Academy of Sciences paglabay sa lima ka adlaw.  Ang radium gilain sa iyang metallic state ni Marie Curie ug André-Louis Debierne pinaagi sa electrolysis sa radium chloride niadtong 1911.[1]

Sa kinaiyahan, ang radium makaplagan sa uranium ug (sa mas gamay nga gidak-on) thorium ores sa mga trace nga kantidad sama ka gamay sa ikapito sa usa ka gram matag tonelada sa uraninite.  Ang radium dili kinahanglan alang sa buhi nga mga organismo, ug ang dili maayo nga mga epekto sa kahimsog lagmit kung kini gilakip sa biochemical nga mga proseso tungod sa radioactivity ug kemikal nga reaksyon niini.  Sa 2014, gawas sa paggamit niini sa nukleyar nga medisina, ang radium walay komersyal nga aplikasyon.  Kaniadto, sa mga 1950s, gigamit kini isip usa ka radioactive source para sa radioluminescent devices ug usab sa radioactive quackery para sa gituohang curative power niini.  Kini nga mga aplikasyon nahimong dili na magamit tungod sa pagkahilo sa radium;  sa 2020, dili kaayo delikado nga isotopes (sa ubang mga elemento) kay gigamit sa radioluminescent device.
