Explanation:
- Radioactivity was discovered by Becquerel.
- Radioactivity emerges from: Nuclear energy.
- Radioactivity is measured by which device Geiger counter.
- Thorium metal is not only magnetic but also radioactive Radioactive element are Plutonium, Thorium, Uranium.
- Alpha rays is a positively charged particle emitted by a radioactive element.
- A negatively charged particle emitted by a radioactive element during radioactive decay is called a beta particle.
- Radioactive isotopes are used in medicine for both diagnostic imaging and treatment.
- A 100 g sample of a radioactive element has a half life of 5 days. 12.5grams of radioactive material will remain after 15 days.
- Radioactive elements have atomic number greater than82.
- Weak Nuclear Force is responsible for the radioactive decay of the nucleus.
- The radioactive material must be placed in a box of Lead.
- Radioactive cobalt 60 is used for curing: Cancerous cells.
- Radioactive isotope present in atmosphere is: carbon -14.
- Unstable nuclei are radioactive.When radioactivity rays are passed through air or any gas, they cause it to Ionize.
