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.

How much does 1 ounce of plutonium cost?
The cost of 1 ounce of plutonium varies based on factors such as purity, market demand, and regulations. It is not typically bought and sold on the open market, but estimates suggest it could be worth several thousand dollars per ounce.
It develops during the night when the ground cools by giving off long wave radiation. The air near the ground is cooled by contact with the ground, and this layer eventually gets cooler than the air higher up. The inversion layer is enhanced by the presence of a large high pressure above, which usually is dry and has only light winds(so there is not much horizontal or vertical mixing).
Convection is the transfer of heat through the movement of fluids (liquids or gases), while radiation is the transfer of heat in the form of electromagnetic waves. Convection requires a medium to carry heat, such as air or water, while radiation can occur through a vacuum. Both processes play important roles in the transfer of heat in various systems and are key mechanisms in maintaining Earth's temperature.
What does the number in radioactivity mean?
The number in radioactivity typically refers to the amount of radioactive material present, measured in units such as becquerels or curies. This number signifies the rate at which the material emits radiation and helps determine the potential health risks associated with exposure.
Whats the frequency of infrared radiation?
The frequency of infrared radiation ranges from about 300 GHz to 400 THz.
What disease can be caused by overexposure to radiation?
The amount and duration of radiation exposure affects the severity or type of health effect.
Cancer is considered the primary health effect from radiation exposure.
Radiation can also cause changes in DNA (the blueprints) that ensure cell repair and replacement. Changes in DNA are called mutations. The mutations can be caused by exposure of the fetus in the uterus and affect only the individual who was exposed. Genetic mutations are passed on to offspring.
Health effects from 'acute' exposure to radiation usually appear quickly. These effects include burns and radiation sickness. Radiation sickness is also called 'radiation poisoning.' It can cause premature aging or death. Symptoms of radiation sickness are: nausea, weakness, hair loss, skin burns or diminished organ function.
Chemical properties of a radionuclide determine where health effects occur. Many organs require certain elements and can't make the difference between radioactive and non-radioactive forms of the element and accumulate it as rapidly as the other.
Examples:
The thyroid needs iodine to function normally, but can't tell the difference between stable and radioactive isotopes. As a result, radioactive iodine contributes to thyroid cancer more than other types of cancer.
Calcium, strontium-90 and radium-226 have similar chemical properties. Then, strontium and radium in the body tend to collect in calcium rich areas, such as bones and teeth. Then, they contribute to bone cancer.

EX) the explosion from the bombing of Hiroshima and Nagasaki wasn't the only thing that caused damage, radiation spread to surrounding areas and caused transmutations in people which can lead to cancer, etc.
At nine fifteen on august sixth in 1945, an atom bomb of fifteen kilotons was dropped on Hiroshima. It was detonated one thousand, eight hundred feet over the ground. The plane that dropped the bomb was the Enola Gay aircraft bomber. The same thing happened on August ninth over Nagasaki. The fatalities of Hiroshima were seventy thousand and Nagasaki forty thousand. The affects of the atomic bomb, or death-causing factors are the blast wave, thermal and nuclear radiation.
Uranium is an Alpha emitter, ingestion of uranium containing materials exposes the body internally to Alpha radiation which can mutate cells causing cancer.
Uranium is also a moderately toxic heavy metal, ingestion of very large amounts could cause heavy metal poisoning.
The obvious answer is that all the energy that comes to Earth from Why_is_heat_radiation_important(solar energy) comes by radiation. All life on our planet depends on that energy, since plants need it to produce their own energy via photosynthesis. Animals that are herbivores derive their energy from eating those plants, and carnivores and omnivores derive their energy from eating other animals.
Are poison and radiation the same?
A definition for poison is something that can be harmful, unpleasant, and fatal. Radiation can be harmful therefor radiation could be a poison.
There is something called acute radiation syndrome which is also called radiation poisoning. This occurs when there is destruction of living tissue due to the effects of being exposed to high levels of radiation.
I guess you mean solar radiation. Most of Mexico falls within the 5.2 - 5.75 KwH per square meter per day. Some areas in northern Mexico, especially on the Sonoran desert have 6.57 - 6.84 KwH/sq m.
For comparison purposes, the solar radiation of several US' cities are provided:
- Los Angeles, CA: 5.62
- Phoenix, AZ: 6.58
- San Antonio, TX: 5.30
- Las Vegas, NV: 6.41
Which is the only type of radiation that might penetrate the walls of a house?
- AM radio waves
- shortwave radio waves
- VHF radio waves
- UHF radio waves
- microwaves
- x-rays
- gamma rays
- neutron radiation
- neutrinos
- secondary cosmic rays
- etc.
For the electromagnetic spectrum the only bands that conventional walls are opaque to are infrared, visible, and ultraviolet light. If the walls have lots of metal in them then they may also be opaque to parts or all of the radio wave and microwave bands.
For particulate radiation the walls will be opaque to all charged particles, unless they are at very high energy (e.g. cosmic rays).
Who was the first person to die of radiation poisoning?
The first fully documented case of true death by radiation poisoning was Marie Curie in 1934 after many years of exposure to different highly radioactive elements and x-rays from medical equipment she used in WW1 to examine wounded soldiers. Even her papers and cookbook are too radioactive to be safely handled without special protective clothing.
In 1932, a famous American socialite called Eben Byersdied after ingesting large amounts of a radium containing patent medicine called Radithor over the course of several years. However the real cause of his death was multiple cancers, not radiation poisoning.
How much radiation is an average person in the USA exposed to each year?
According to NCRP Report #93, "Ionizing Radiation Exposure of the Population of the United States" (1987) the average exposure is about 295 mRem of Natural Background Radiation and about 63 mRem from Manmade Radiation (medical + consumer products) . Most (about 67%) of the natural background radiation is from inhaling Radon gas.
Which type of electromagnetic radiation is used in baggage scanners, and why?
X-rays, because they either pass through or are absorbed by the objects in the baggage, creating an image of the objects. -Apex :)
