Unit Explanations
Radiation Absorbed Doserad
Source UnitThe rad (radiation absorbed dose) is a non-SI unit that quantifies the amount of ionizing radiation energy absorbed by a material, particularly human tissue. One rad is equivalent to the absorption of 0.01 joules of energy per kilogram of matter. This unit is mainly used in the fields of radiation protection and radiological science to assess the biological effects of radiation exposure. The concept of the rad was developed to help in the understanding of the dose-response relationship of radiation exposure and its potential biological effects.
Current Use
The rad is currently used primarily in the United States for measuring absorbed radiation in medical, environmental, and occupational settings. It aids in determining appropriate radiation exposure levels for patients undergoing treatments such as cancer therapy and helps in assessing risks in occupational settings involving radiation.
Fun Fact
The rad was once widely used in medical settings, particularly in oncology, before the adoption of the gray.
RutherfordRd
Target UnitThe rutherford (Rd) is a unit of radioactivity defined as the activity of a sample that produces one million disintegrations per second. It is primarily used in the field of nuclear physics and radiation measurement. The rutherford is not part of the International System of Units (SI), but it serves as a useful measure for describing the rate of decay of radioactive materials. In practical terms, one rutherford is equivalent to 1,000,000 disintegrations per second. This unit was developed to quantify the intensity of radioactive emissions from isotopes.
Current Use
The rutherford is primarily utilized in specialized fields such as nuclear physics, radiobiology, and nuclear engineering. It serves as a measure of the activity of radioactive isotopes, especially in research contexts. While its use has diminished with the adoption of the becquerel as the standard SI unit, the rutherford can still be found in historical texts and specific scientific discussions. Laboratories that deal with high levels of radioactivity often refer to rutherford values for practical guidance in experiments and safety measures.
Fun Fact
Ernest Rutherford is known as the father of nuclear physics for his pioneering work in understanding radioactivity.
