Why do people working around radioactive waste in a radioactive storage facility wear badges that contain strips of photographic film?
The film in the badges changes colour when radiation hits it. By looking at the badges, the people wearing them can tell how much radiation they have been exposed to. They have different strips of film for different types of radiation, so they are not only able to tell how much radiation someone has been exposed to, but also what type of radiation. Its basically a safety measure to ensure that workers are not exposed to excessive levels of radiation emitted from the waste.
What type of radiation is emitted when polonium 212 forms lead 208?
In this case alpha particles are emitted.
Definition for Radioactive decay?
Radioactive decay is the characteristics of radioactive substances that all radioactive atoms do not disintegrate at once but do so gradually .It is spontaneous and it is not influenced by external conditions such as temperature, pressure , etc.. In any radioactive decay , either an alpha particle or beta particle is emitted by atom .Both the particles are not emitted simultaneously .Moreover , the atom does not emit more than one alpha particle or more than one beta particle at a time
What happens when carbon 14 undergoes radioactive decay?
6C14 ---------> 7N14 + -1 e0 Beta particle is emitted and carbon changes into nitrogen
Radioactive decay is the most dangerous?
There are three types: Beta decay, alpha decay, and gamma decay/gamma rays. They are all dangerous if exposed to a high amount of radioactive matter. When the radioactive isotope undergoes beta, alpha, and gamma decay, there is an emission of a beta particle, alpha particle, and gamma ray (respectively). In highly radioactive matter, there are often trillions of radioactive isotopes that emit these particles and/or rays - and they are very high-energy once emitted. However, they are only dangerous when exposed to a high amount.
What is the scientific calculation of radiation emitted from various radioactive sources is?
I would expect the total radiation to be equal to the sum of the individual radiations.
Which of the following is not a component of the radiation emitted by a radioactive sample a.alpha radiation b.delta radiation c.gamma radiation d.beta radiation?
Radioactive substances can emit alpha particles, gamma radiation (gamma rays) and beta radiation (beta particles). What they do not emit is delta radiation.It causes transmutation.It has a mass of 4 amus.
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.
Why radiation is emitted from radioactive substance?
Radiation is emitted from radioactive substances due to the spontaneous decay of unstable atomic nuclei. This decay process releases energy in the form of particles or electromagnetic waves, which are collectively referred to as radiation.
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.
Are x-rays emitted during radioactive decay?
Yes they are. Nearly all kinds of electromagnetic radiation are emitted during radioactive decay
What happens to a radioactive atom after it has emitted its radiation?
The initial atom is transformed in another atom.
The electromagnetic radiation that is emitted from radioactive elements is released in the form of .?
The electromagnetic radiation emitted from radioactive elements is released in the form of gamma rays. Gamma rays are high-energy photons that are produced during radioactive decay processes, such as alpha and beta decay. This radiation is highly penetrating and can travel significant distances through matter.
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.
Are gamma rays emitted by radioactive elements?
Yes, gamma rays are a type of electromagnetic radiation emitted by radioactive elements during radioactive decay processes. They are high-energy photons with no mass or charge, and can penetrate through materials easily.
Minimum frequency generated by radioactive nuclei?
The minimum frequency of radiation emitted by a radioactive nucleus is proportional to its energy. This frequency is related to the energy by the equation E = hf, where E is the energy, h is Planck's constant, and f is the frequency. Therefore, the minimum frequency of radiation emitted by a radioactive nucleus depends on the specific energy released during the radioactive decay process.
What is a radiation injury?
Radiation injuries are caused by ionizing radiation emitted by sources such as the sun, x-ray and other diagnostic machines, tanning beds, and radioactive elements
