62 Roentgen = 0.015996 Coulomb per kilogram
Conversion Formula
Unit Information
Roentgen
A traditional unit of exposure to X-rays and gamma rays. Defined as the amount of radiation that produces one electrostatic unit of charge in one cubic centimeter of dry air. Named after Wilhelm Röntgen.
Coulomb_per_kilogram
The SI unit of exposure to ionizing radiation. Defined as the amount of radiation required to create one coulomb of charge in one kilogram of air. Used primarily for X-ray and gamma radiation.
Conversion Tips
- Remember to check your decimal places for accuracy.
- This conversion is commonly used in international applications.
- Consider the context when choosing precision levels.
- Double-check calculations for critical applications.
Learn More About Radiation
Scientific Overview
Radiation is the emission or transmission of energy in the form of waves or particles through space or through a material medium. This includes electromagnetic radiation, particle radiation, and acoustic radiation.
Historical Background
Radiation was systematically studied starting with Wilhelm Röntgen's discovery of X-rays in 1895. Henri Becquerel discovered radioactivity in 1896, and Marie Curie made pioneering contributions to radiation research. The field advanced significantly with the development of quantum mechanics.
Real-World Applications
Medical Imaging
X-rays, CT scans, and nuclear medicine use radiation for diagnosis.
Cancer Treatment
Radiation therapy destroys cancer cells using high-energy radiation.
Nuclear Power
Controlled nuclear reactions generate electricity through radiation processes.
Food Preservation
Radiation extends shelf life by destroying microorganisms.
Scientific Research
Used in materials analysis, dating techniques, and fundamental physics.
Interesting Facts
- Bananas are naturally radioactive due to their potassium-40 content.
- The human body contains radioactive carbon-14 and potassium-40.
- Cosmic background radiation is remnant from the Big Bang.
- Radiation follows the inverse square law with distance.
- Some organisms can survive extremely high radiation doses.
