How is radiation made?

Radiation can come from many sources but all sources that produce radiation do so because of an abundance of energy that they possess. If you want to produce radiation light a candle. The only energy you will need to do this is a lighted match. When you light the candle wick it burns wax from the candle. This wax is stored energy that you have released as radiation in the form of light. I hope this answer is not too trite. gravity guru.

What is radiation thermometry?

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).

What is infared radiation?

Infrared radiation is a type of electromagnetic radiation with longer wavelengths than visible light. It is not visible to the human eye but is commonly associated with heat. Infrared radiation is used in various applications, such as thermal imaging and communication technologies.

What is re radiation?

it means for example the sun heats the sand and the sands heats your feet

What is hybrid radiation?

Hybrid radiation refers to a combination of different radiation therapy techniques, such as external beam radiation and brachytherapy, used together to treat cancer. This approach allows for more precise targeting of the tumor while minimizing radiation exposure to surrounding healthy tissue.

What are the three kinds of radiation?

· Alpha - a helium nucleus · Beta - a high speed electron · Gamma - an electromagnetic radiation of wavelength about 10-14 m.

What is Gamma radiography process?

Gamma radiography is a non-destructive testing method that uses gamma radiation to create images of the internal structure of an object. A gamma source is placed on one side of the object, and a film or digital detector on the other side captures the radiation that passes through, creating a shadow image of any defects or features within the object. This method is commonly used for inspecting welds in pipelines, vessels, and other critical structures.

Most dangerous type of radiation?

Gamma radiation is considered the most dangerous type of radiation due to its high energy and ability to penetrate deep into tissues, causing damage at the cellular level. Exposure to high levels of gamma radiation can lead to severe health effects, including radiation sickness, DNA damage, and an increased risk of cancer.

What is active radiation?

Active radiation refers to electromagnetic radiation that carries sufficient energy to ionize atoms or molecules, such as X-rays and gamma rays. This form of radiation can cause damage to living tissue and is used in various applications such as medical imaging and cancer treatment. It is important to handle active radiation with caution and use proper safety measures.

Unit of radiation?

The unit of radiation is the Gray (Gy), which measures the absorbed dose of ionizing radiation in tissue. Another common unit is the Sievert (Sv), which adjusts the absorbed dose to account for different types of ionizing radiation's varying biological effects on human health.

What is radiation loss?

Radiation loss refers to the energy emitted by an object in the form of electromagnetic waves, such as heat or light. This process is often associated with the cooling of an object as it releases energy in the form of radiation.

What happens in radiation?

Radiation is the transfer of energy in the form of waves or particles through space. It can have various effects depending on the type and intensity of the radiation, ranging from ionizing cells and causing DNA damage in high doses (such as in nuclear accidents) to being used for medical purposes like cancer treatment and diagnostic imaging.

What are examples of radioactivity?

Examples of radioactivity include the decay of uranium and thorium in rock formations, the emission of gamma rays from the sun and other celestial bodies, and the use of radioactive isotopes in medical imaging and cancer treatment.

What radiation is given off by a nuclear bomb?

  • prompt (at time of explosion) - neutron, gamma, x-ray, UV, visible, thermal (IR), some radio.
  • delayed (fallout) - beta, gamma, some alpha.

Types of radiation called "ionizing radiation" - alpha, beta, gamma, x-ray, neutron.

What type of radiation is emitted only during detonation?

None.

All types of radiation emitted by an exploding nuclear device are also emitted under other conditions, including natural conditions.

These types of radiation are: alpha, beta, gamma, neutron, x-rays, IR, visible light, UV, EMP.

Some types of naturally present radiation NOT produced by exploding nuclear devices are: cosmic rays, muon showers, proton.

What is radiation poisoning?

An illness caused by an overdose of ionizing radiation. Early symptoms include skin burns resembling bad sunburn, nausea, vomiting, and explosive diarrhea. Later symptoms include hair loss, immune system failure (and uncontrollable infections), and death. If you recover there is a greatly increased chance of cancer and other complications in the long term.

Who discovered radiation?

Wilhelm Röntgen was the discoverer in 1895 of what we usually think of when we hear the term "radiation." More specifically, Röntgen discovered x rays. Marie Curie did coin the term "radioactivity," but it was the French physicist Henri Becquerel who actually discovered radioactivity in 1896. Even that last point is in dispute-there are those who argue that the French chemist Niepce de Saint Victor should be given credit for the discovery.

What is Bharat radiation?

There is no specific term "Bharat radiation." It is possible that you are referring to radiation exposure in India or a type of radiation therapy used in India, but without more context it is difficult to provide a precise answer.

What are facts about microwaves?

  • They are radio waves
  • Their wavelengths range from 3,000 to 30,000 MHz
  • Their wavelengths can be measured in centimeters
  • They are good for transmitting information because they can penetrate haze and smoke
  • Radar works by reading microwave reflections
  • There is a cosmic microwave background radiation filling the universe - it is thought to be left over from the Big Bang
  • In 1946 Dr. Percy Spencer discovered that microwaves could heat anything with water in it
  • Microwave ovens use a magnetron to create the microwaves

Why is radiation harmful to both living and nonliving things?

This depends on the kind of radiation. Most electromagnetic radiation is harmless (e.g. broadcast radio) or only very slightly harmful (e.g. microwave, infrared, and visible light can cause heating of materials and thus thermal changes). However very high energy electromagnetic radiation (e.g. ultraviolet, x-ray, gamma ray) and the particulate radiation of radioactive decay and cosmic rays has enough energy to break the bonds holding molecules together, causing chemical changes.

How radiation discovered?

In 1896 Henri Becquerel was using naturally fluorescent minerals to study the properties of x-rays, which had been discovered in 1895 by Wilhelm Roentgen. He exposed potassium uranyl sulfate to sunlight and then placed it on photographic plates wrapped in black paper, believing that the uranium absorbed the sun's energy and then emitted it as x-rays. This hypothesis was disproved on the 26th-27th of February, when his experiment "failed" because it was overcast in Paris. For some reason, Becquerel decided to develop his photographic plates anyway. To his surprise, the images were strong and clear, proving that the uranium emitted radiation without an external source of energy such as the sun. Becquerel had discovered radioactivity.

Becquerel showed that the radiation he discovered could not be x-rays. X-rays are neutral and cannot be bent in a magnetic field. The new radiation was bent by the magnetic field so that the radiation must be charged and different than x-rays. When different radioactive substances were put in the magnetic field, they deflected in different directions or not at all, showing that there were three classes of radioactivity: negative, positive, and electrically neutral

So basically radiation was discovered by accident

What is radiation concentration?

Radiation concentration refers to the amount of radiation present in a specific area or substance. It is usually measured in units such as becquerels or curies and indicates the density or level of radioactive particles or energy. Monitoring radiation concentration is important for assessing potential health risks and ensuring safety in environments where radiation may be present.

What is invisible radiation?

Invisible radiation refers to electromagnetic waves that are not visible to the human eye, such as ultraviolet light, X-rays, and gamma rays. Although these forms of radiation cannot be seen, they can have various effects on living organisms and materials. Protection measures are often required when working with invisible radiation to prevent harmful exposure.

Does ovens have radiation?

Yes, ovens do emit radiation in the form of infrared heat when they are in use. This is what heats up and cooks the food inside the oven. However, this type of radiation is not harmful to humans in the way that ionizing radiation (such as X-rays or gamma rays) can be.
