What is a rad? The rad (radiation absorbed dose) is a unit of absorbed dose of ionizing radiation in the US customary system, equal to 0.01 grays or 100 ergs per gram. The rad definition makes it used in the United States for radiation physics and medical applications, though the gray is the preferred SI unit. The rad measures the amount of energy absorbed by matter from ionizing radiation. One rad equals 0.01 grays, making it a smaller unit than the gray.

Converting rads to other radiation units is essential for radiation physics and medical applications, especially for international communication. One rad equals 0.01 grays, 0.01 sieverts (for X-rays and gamma rays), 1 rem (for X-rays and gamma rays), or 10 milligrays. Rad conversions are fundamental to absorbed dose measurements in countries using US customary units, whether you're using a rad converter tool, learning how to convert rads, or performing rad to other units calculations. The rad's practical scale makes it ideal for everyday absorbed dose measurements in countries using US customary systems.

The rad is used in the United States for radiation physics and medical applications. A rad converter is valuable for radiation calculations, physics applications, and medical physics. While the gray is increasingly used internationally, the rad remains in use in certain US contexts, making rad converter tools valuable resources for professionals in radiation physics and medical physics.

What is a curie? The curie (Ci) is a unit of radioactivity in the US customary system, named after Polish-French physicist Marie Curie. The curie definition identifies one curie as 3.7 × 10^10 becquerels, originally based on the activity of one gram of radium-226. The curie is a very large unit, representing a significant amount of radioactivity. The curie is used in the United States for measuring high-activity radioactive sources, though the becquerel is the preferred SI unit.

Converting curies to other radioactivity units is essential for understanding high-activity radioactive sources and radiation measurements. One curie equals 3.7 × 10^10 becquerels, 37,000 rutherfords, 37 billion decays per second, or 37,000 kilobecquerels. Curie conversions are fundamental to high-activity radioactivity measurements, whether you're using a curie converter tool, learning how to convert curies, or performing curie to other units calculations. The curie's practical scale makes it ideal for expressing very high radioactivity levels, providing a convenient unit for measurements that are too large for becquerels but represent common high-activity source levels.

The curie is used in the United States for measuring high-activity radioactive sources, particularly in nuclear medicine and industrial applications. A curie converter is valuable for radiation calculations, safety assessments, and nuclear medicine applications. While the becquerel is increasingly used internationally, the curie remains in use in certain US contexts for high-activity measurements, making curie converter tools valuable resources for professionals in nuclear medicine and radiation protection.
