Is it true radioactive material and radiation are unnatural-they did not exist on earth until creatd by scientists?
Radioactive materials and radiation existed long before scientists. Radiation occurs naturals in the air we breath, in the food we consume, in the earths crust and in the water we drink. We in 3.5 million radioactive molecules every time we take a breath. In a about a year we consume 240 mrem of raditaion naturally from theses causes.
What else can I help you with?
Would exposure to something which is radioactive make you radioactive?
Not much. There are various forms of radioactivity. A material can emit alpha particles, beta particles (high energy electrons), neutrons, gamma rays (high energy photos), or you can ingest it. If you eat, breathe or inject a radioactive material, it will be inside you and you will become "radioactive" in that you will emit particles or radiation. This is how PET works - the doctor injects a short-lived isotope and tracks the positrons emitted by them with a detector, so can track, say, the uptake of glucose in your brain. If you sit on a lump of radioactive material, the radiation will damage your skin and body to an extent depending on the intensity and type of radiation. If an emitted particle changes an atom in your body to an unstable isotope, this will later decay by emitting a particle itself. In this sense you will have been made "radioactive". This is I believe very unlikely - the side effects of radiation damage would kill you long before you had become significantly radioactive just from contact. A particle is more likely to break chemical bonds and create free radicals than to create a new isotope.
What is the name for the emission of rays and particles by a radioactive material?
The name for the emissions of rays and particles by a radioactive material are called radioactive decay. There are many different types of radioactive decay that emit different rays and particles.
A synthetic element that is used in smoke detectors is?
Americium-241 this is an emitter of alpha radiation, which is used in smoke detectors as it is very ionising and will not be able to travel through smoke. Therefore, in a fire the detector will not receive any alpha radiation and hence the alarm will go off.
How are stratigraphic and radioactive dating different in regards to how they date fossils?
Radioactive dating refers to the process of measuring the age of an object using the amount of a given radioactive material it contains. Relative dating, meanwhile, measures the order of past events, without determining their absolute age.
Why does radioactive parent material break down into daughter material?
A fundamental property of radioactive material is that the atomic nucleus has an unstable configuration. The nucleus of a single atom of such material may break down at any instant, or may never break down at all, but with a large number of atoms in a collection, there is a statistical probability that half of them will break down in a given amount of time, which is known as the "half life" for that radioactive material. Exactly why this should be so is a mystery which cannot be adequately explained, but is observed and accepted as such. A deeper understanding of this phenomenon would probably give us a better insight into the true nature of the universe as a whole.
What are three physical factors that have no effect on the amount of radiation emitted by a radioactive source?
The half-life of the radioactive material, the type of decay process, and the initial quantity of radioactive material are physical factors that do not affect the amount of radiation emitted by a radioactive source. Radiation emission is solely determined by the intrinsic properties of the radioactive material itself.
How many radiation do radioactive material emit?
Radioactive materials emit particles or energy in the form of radiation. The amount of radiation emitted by a radioactive material depends on its specific properties and decay process. Radiation is typically measured in units such as becquerels (Bq) or curies (Ci), which indicate the rate of radioactive decay.
Does the amount of radiation you give off depend on what is inside of you?
Yes. Radiation is emanated from radioactive material, so the amount of radiation that someone "gives off" is a function of how much radioactive material they have inside them.
How do you prepare gamma radiation?
Gamma radiations is a natural process by radioactive material.
What is defreent between radioactve and nuclear material?
Radioactive material refers to substances that emit radiation spontaneously, while nuclear material is any material that can undergo nuclear reactions such as fission or fusion. Essentially, all radioactive material is nuclear material, but not all nuclear material is necessarily radioactive.
What type of device includes any point source that emits radiation without actively dispersing radioactive material across an area?
A point source device that emits radiation without actively dispersing radioactive material across an area is commonly referred to as a sealed radiation source. Such sources are contained within a sealed casing or structure that prevents the escape of radioactive material.
Why the radioactive material must be placed in a box of lead?
Radioactive materials emit dangerous radiation; most of this will be blocked by a box of lead.
Which type of devices includes any point source that emits radiation without actively dispersing radioactive material across an area?
Devices that include any point source that emits radiation without actively dispersing radioactive material across an area are considered sealed radiation sources. These sources are contained within a sealed container or device, preventing the spread of radioactive material.
What type an amount of radioactive material is found in the M43A1 detector?
The M43A1 detector contains a small amount of radioactive material typically in the form of a sealed radioactive source, such as cesium-137 or americium-241. This radioactive material is used to generate radiation for detection purposes in the detector.
Which type of device includes any point source that emits radiation without actively dispersing radioactive material across the area?
A point source that emits radiation without actively dispersing radioactive material is typically found in radiation therapy devices, such as linear accelerators used for cancer treatment, or in certain types of industrial radiography equipment. These devices focus and direct radiation beams toward a specific target area, without spreading radioactive material around.
The scientific calculation of the radiation emitted from various radioactive sources is?
done using mathematical models that consider factors like the type of radioactive material, its half-life, decay mode, and the distance from the source. This allows scientists to predict radiation levels and risks to human health or the environment. Sophisticated tools like Geiger counters and dosimeters are also used to measure radiation levels accurately.
Is there any radioactive material in microwave ovens?
There are no radioactive materials in microwave ovens: they use microwaves to cook food and heat liquids.
