| Specification: |
Radon (CAS NO.10043-92-2) is also called Alphatron ; HSDB 6369 ; Niton /(222)Radon ; Radium emanation ; Radon, radioactive ; UNII-Q74S4N8N1G . Radon (CAS NO.10043-92-2) is colourless gas. It is radiochemically unstable and chemically unreactive. |
| Report: |
NTP 10th Report on Carcinogens. |
| Flash Point: | °C |
| Color: | Colorless gas Can be condensed to a colorless, transparent liquid & to an opaque, glowing solid. When cooled below the freezing point, radon exhibits a brilliant phosphorescence which becomes yellow as the temperature is lowered and orange-red at the temperature of liquid air. Solid form exists as face-centered cubic crystals at normal pressure. |
