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.
What type of device includes any point source that emit radiation without actively dispersing radioactive material?
Radiological Exposure Devices (REDs)
What is the process by which an unstable isotope will emit nuclear radiation until it has a stable number of protons and neutrons called?
radioactive decay
Is actinium a very powerful source of alpha radiation?
Yes, the isotope 227Ac emit alpha and beta radiations; all the isotopes of actinium are radioactive and emit radiations.
What is a nonradioactive material?
A non-radioactive element is an element that has at least 1 isotope that is not radioactive. The means that at least one isotope has a stable nucleus that does not break down by shooting off high-energy particles.
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.
At what temperature does Lithium-6 emit radiation?
Any material will emit blackbody radiation at any temperature. Lithium 6 will never emit ionizing radiation.
What type of device includes any point source that emit radiation without actively dispersing radioactive material?
Radiological Exposure Devices (REDs)
Why are some isotopes called radioactive?
These isotopes are unstable and emit radiation.
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.
Which type device includes any point source that emit radiation without actively dispersing radioactive material across an area?
Radiological Exposure Devices (REDs)
What is the spontaneous process through which unstable nuclei emit radiation?
Radioactive decay or radioactivity
What radiation can be ingested?
Radiation per se cannot be ingested Many radioactive compounds can be ingested These emit radiation. Iodine for example exists in a radioactive form that is ingested to treat certain thyroid conditions.
Why are radioactive pigments not used?
Radioactive pigments are not used because they emit radiation. It's unsafe, especially for children and pregnant women.
What is the process by which some substances spontaniously emit radiation?
All elements with an atomic number >83 are naturally radioactive
What eventually happen to all radioactive isotopes?
They emit particles, electromagnetic radiation, or both.* Apex*
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.
