Radiation thermometry is the basic method for non-contact temperature measurement.
It is called by many names as explained on an informative page of the About Temperature Sensors website (http://www.temperatures.com/rts.html). The same page contains many links to related web resources.
The website IRWeb.INFO, is an open resource on applications information of IR, or Infrared Thermometers, one of the alternate names for radiation thermometry.
Temperature measurement by this method is subject to many error sources and selection of a radiation thermometer to perform a given task can be optimized, if one understands the relationship between the various factors; however, it is not always easy.
One of the major problems using this technology is the difficulty in verifying that a given measurement is within acceptable error.
Despite these facts, there are countless successful applications as detailed on the above two websites and in two notable publications, both with the late Professor Emeritus David P. DeWitt of Purdue University as a co-author: (1) Therory & Practice of Radiation Thermometery (DeWitt, D.P & Nutter E.A. Wiley Interscience) and (2) Applications of Radiation Thermometery (Richmond & DeWitt; ASTM -available for download on the ASTM.org bookstore).
Infrared radiation, infrared, heat radiation.
Natural background radiation
Secondary radiation refers to the radiation that is produced when primary radiation interacts with matter, leading to the emission of additional radiation. This secondary radiation can have different properties and energies compared to the original primary radiation.
There are two main types of radiation: External Radiation External radiation is the most common type of radiation, typically given after lumpectomy and sometimes, mastectomy. Internal Radiation Internal radiation is a less common method of giving radiation. It is being studied for use after lumpectomy.
Nuclear weapons emit various types of radiation, including gamma radiation, neutron radiation, and thermal radiation. These forms of radiation can have harmful effects on living organisms and the environment.
A thermometer is a device used to measure temperature. It typically consists of a temperature sensor (like mercury or digital probe) and a scale for displaying the temperature reading in degrees Celsius or Fahrenheit. Thermometers are commonly used in various applications, including medical, environmental, and industrial settings.
