What does being radioactive mean?
Exhibiting or caused by radioactivity.Radioactivity: the spontaneous emission of a stream of particles or electromagnetic rays in nuclear decay.Examples are radioactive isotopes [an unstable nucleus that undergoes radioactive decay], radioactive dating [the process by which the approximate age of an object is determined based on the amount of certain radioactive nuclides present], and radioactive decay [the spontaneous disintegration of a nucleus into a slightly lighter and more stable nucleus, accompanied by emission of particles, electromagnetic radiation, or both.]
Is there a picture of polonium and radium?
Polonium and radium are both radioactive elements that cannot be photographed because they are not visible to the naked eye and require specialized equipment to detect. They emit radiation that can be harmful to living organisms.
What band of light is destructive to life on earth and is diminished by the ozone layer?
Ultraviolet (UV) radiation from the sun is the band of light that can be destructive to life on Earth. The ozone layer protects Earth by absorbing a significant portion of the sun's harmful UV radiation, reducing its impact on living organisms.
Why are bannanas radioactive?
Nearly all living things contain a certain amount of radioactive material, mainly radioactive Carbon. Bananas absorb large amounts of Potassium, therefore also absorbing radioactive Potassium 40.
What is Gy radiation?
Gamma radiation (γ radiation) is a type of ionizing radiation that is composed of high-energy photons. It is emitted during radioactive decay processes and can penetrate deeply into materials, making it potentially damaging to living organisms. Protection measures such as shielding are important when working with sources of gamma radiation.
What are the things with radiation?
Things with radiation include nuclear power plants, X-ray machines, radioactive waste, and certain types of medical treatments like radiation therapy for cancer. Radiation can be harmful to living organisms if not properly controlled and managed.
What are some ways in which radioactive elements can be dangerous?
Radiation, even in small doses, can cause cancer in humans and other living things Alpha radiation is responsible for most of the damage of DNA in living cells
What is meant by radio active elements?
Radioactive elements are atoms that are unstable and undergo a process called radioactive decay, where they release energy in the form of radiation. This radiation can take various forms such as alpha particles, beta particles, and gamma rays, and can be harmful to living organisms if exposure occurs.
What is the difference between radioactive and non radioactive materials?
Radioactive materials contain unstable atoms that decay and emit radiation, while non-radioactive materials do not emit radiation. Radioactive materials can be harmful to living organisms due to their ionizing radiation, whereas non-radioactive materials are generally considered safe for everyday use.
Are humans naturally radioactive?
No, humans are not naturally radioactive. While all living organisms contain trace amounts of radioactive elements, the levels are very low and not considered harmful.

All living things on earth are radioactive true or false?
False. Not all living things on Earth are radioactive. Radioactivity is a natural process that can be found in some elements and materials, but it does not apply to all living organisms.
Only nonliving things are radioactive?
No. All things are radioactive, including living things and even humans. All matter (save a few) emits gamma radiation spontaneously.
Introduction of radioactive?
Radioactive materials are substances that emit radiation in the form of particles or electromagnetic waves due to the unstable nature of their atomic nucleus. This radiation can be harmful to living organisms and can cause damage to cells and DNA. Radioactive materials are commonly used in medicine, industry, and research, but they need to be handled and disposed of carefully to minimize the risks associated with their radiation.
What is radiation rain?
Radiation rain is a phenomenon where radioactive particles are carried by rainwater from the atmosphere to the ground. This can occur after a nuclear incident or explosion, leading to radioactive contamination of the environment. It poses significant health risks to living organisms exposed to the contaminated rainwater.
What Happens when material becomes radioactive?
When material becomes radioactive, it starts emitting radiation in the form of alpha, beta, or gamma particles. This radiation can be harmful to living organisms by causing damage to cells and DNA, leading to health risks such as cancer or radiation sickness. The level of risk depends on the type and amount of radiation emitted, as well as the duration of exposure.
