Radiation
Radiation is a process of radioactive waves affect and mutate living cells. There are several types of radioactive waves, and radiation effects. In this category, there are questions pertaining to the causation and effects of radiation.
263 Questions
What are some negative long-term effects of nuclear radiation?
Many different birth defects and lukemia.
What are the dangerous rays produced by mobile phones?
Microwaves.... Mobiles transmit their data and calls using high frequency radio waves. Ongoing study seems to suggest that long-term use of the handset to make calls 'may' heat the part of the brain closest to the phone's built-in antenna. However - there is still much research to be done. If you're concerned enough - use a bluetooth headset.
How are isotopes used to keep food from spoiling?
Typically, dehydration and irradiation. The causes of most food spoilage is the growth of bacteria in the moist environment of the food. Irradiation can kill all the bacteria, so as long as the package is sealed, no bacteria can grow there. And dehydration removes most of the water from the food so that it takes up less space and weight, and stays edible for longer times.
Which of the folowing best describes alpha particle beta particles and gamma rays?
All three are the natural products of the decay of certain radionuclides. An alpha particle is basically the nucleus of a helium atom; a beta particle is an electron; a gamma ray is a photon of high-energy gamma radiation.
What is bremsstrahlung radiation?
bremsstrahlung is german and translates as breaking or slowing down rapidly.
bremsstrahlung radiation is the electromagnetic radiation emitted when a charged particle slows rapidly.
Is radiation a natural disaster?
No. Radiation is always present in the environment and in most cases is harmless. In some regions there is a problem with natural radon, a radioactive gas, working its way into homes, but this is an issue that must be addressed one building at a time. Large-scale disasters involving radioactive materials are the result of humans who have taken such materials from the environment and concentrated them into forms we can use.
Is nuclear radiation a bad or a good thing?
Nuclear radiation is neither good nor bad, it is a natural phenomenon. Natural phenomena cannot be good or bad (this is an ethical/moral judgement), they are simply facts.
What is beta radiation properties?
Beta particles or radiation is an electron emitted at high speed or energy from some types of unstable elements in a process known as beta-decay.
Beta radiation is not healthy for living things. It is usually stopped by a few millimeters of metal, wood, or plastic. Direct exposure to the skin can cause radiation burns.
Radiation is exactly waht it sounds like... Nuclear energy would be running through you're system slowly killing you :)
Where was radiation discovered?
- Wilhelm Röntgen working in Germany discovered X-rays in 1895.
- Henri Becquerel working in France discovered spontaneous radioactivity in samples of Uranium salts in 1896.
Radiation is energy that comes from a source and travels through some material or through space.
Since there is Vacuum( empty space) between earth and the sun, Light travels using radiation....
Hope it helped! :)
Polar radiation refers to solar energy received by the Earth's polar regions, particularly the North and South Poles. Due to the Earth's axial tilt and orbit, the polar regions receive sunlight at a lower angle compared to equatorial regions, leading to variations in the amount and intensity of solar radiation received throughout the year. This differential heating is a key factor influencing the climate and environmental conditions in polar areas.
What type of radiation does radium give off?
Radium emits alpha, beta, and gamma radiation.
Alpha radiation is fully ionized helium nuclei. Beta radiation is high energy electrons. Gamma radiation is very high energy electromagnetic radiation. All of these can do significant damage to living things.
What element used as shield for radioactivity?
It depends somewhat on the type of radiation that one needs to be shielded.
Lead is very effective for gamma rays, however if the radiation is mostly neutron radiation then borated reinforced concrete is much more effective than lead (the hydrogen in the water of crystallization in the concrete slows the neutrons and the boron then absorbs the slow neutrons). Nuclear reactors which produce intense radiation of both gamma ray and neutron often use alternating layers of lead plate and borated reinforced concrete for shielding.
If all you are shielding against is beta radiation then a sheet of aluminum foil is typically adequate.
If all you are shielding against is alpha radiation then your skin (do not ingest or inhale alpha emitters) or one sheet of paper is adequate.
What are the three most common type of radiation in chemistry?
The most common radiations are alpha, beta and gamma.
No, steam is matter: water in its gas state.
However being quite hot steam is emitting far more electromagnetic radiation (in the infrared band) than liquid water does.
EM radiation higher in frequency than violet visible light but lower in frequency than soft x-rays.

Would you classify radiation as ionizing radiation?
Yes, radiation can be classified as either ionizing or non-ionizing. Ionizing radiation has enough energy to remove tightly bound electrons from atoms, leading to the formation of ions. Examples of ionizing radiation include X-rays, gamma rays, and certain types of nuclear radiation.
How is radiation oncology used?
A radiation oncologist may utilize external beam radiation treatment to treat disease. Outside bar radiation treatment can be created by a machine that quickens electrons to deliver x-beams or gamma beams. Proton treatment is another type of outside pillar radiation treatment that utilizes cyclotrons to deliver charged particles that wreck tumors. Radiation treatment given by radioactive sources that are put inside the patient. The radioactive sources are fixed in needles, seeds, wires, or catheters, and embedded legitimately into or approach a tumor on an impermanent or lasting premise. Brachytherapy is a typical treatment for diseases of the prostate, uterus, cervix or breast. Some malignancy patients might be treated with radiation as their essential treatment. At times, radiation oncology is given simultaneously as chemotherapy. Chemotherapy utilized with radiation treatment or radiation oncology can improve the neighborhood reaction and lessen metastatic sickness.
