Transcript of Radon
Radon gas is a byproduct of the radium salt used for the glowing numbers and hands on vintage clocks and watches. Radon is a colorless, odorless, radioactive, and tasteless gas Radon was discovered in 1900 by Friedrich Ernst Dorn, who called it niton. It is essentially inert. It has been called radon since 1923, before which it was called niton after the Latin word for shining, nitens. Today, radon is still primarily obtained through the decay of radium.
Radon has been present in the earth's crust for billions of years. It is produced by the natural disintegration of radium, which is a lustrous, white radioactive element produced by the decay of uranium, and sometimes found in rock or bedrock. Before radon was discovered to be hazardous to human health, homes in the American West were sometimes built with materials contaminated by the radium from uranium mines. History of Radon Atomic Number: 86
Atomic Weight: 222
Melting Point: 202 K (-71°C or -96°F)
Boiling Point: 211.45 K (-61.7°C or -79.1°F)
Density: 0.00973 grams per cubic centimeter
Phase at Room Temperature: Gas
Element Classification: Non-metal
Period Number: 6 Group Number: 18 Group Name: Noble Gas Basic Info Facts 1. Radon gas is the the #1 cause of lung cancer in non-smokers. 2. Radon is a radioactive noble gas. 3. About 21,000 deaths per year are attributed to radon gas exposure. 4. When cooled to a solid state, it glows yellow and then orange-red as the temperature falls. 5. Elevated radon levels are found in all 50 states in the US and across Canada. 6. Radon is the byproduct of the gas evaporated from Radium. 7. Radon moves more rapidily through permeable soils, such as coarse sand and gravel, than through impermeable soils, such as clays. Fractures in any soil or rock allow radon to move more quickly. Uses: Radon Seed Therapy:
A radon seed is a small tube of radon gas that doctors surgically implant into the middle of a tumor. The radiation energy from the radon focuses specifically on the cancerous cells, killing them. On occasion, radon seeds have caused secondary tumors to develop. Radon Seeds Penny Radon Spas:
Radon gas is frequently used as a therapeutic treatment for arthritis in many European countries. People with various forms of arthritis go to radon spas and clinics to deliberately expose themselves to radon. Those without the money to buy radon treatment often go to old mines with high concentrations of radon in the air. 87 Protons
