A sample contains 1200 radioactive atoms of a particular nuclide After an interval of two half-lives how many atoms have disintegrated?
Petrok
After two half life it must be 1200 x 1/2 x 1/2 = 300 atoms.

What is the name of the series which contains most of the synthetic and radioactive elements?
All of the actinides are radioactive, and almost all are synthetic.
Region of the periodic table where most radioactive elements are found?
Group 3 of the periodic table contains many of the radioactive elements.
What is radioactive fossil?
There is no such thing as a "radioactive fossil." Fossils are remains or traces of ancient organisms preserved in rock or sediment. Radioactive materials or isotopes can be found in certain rocks where fossils are found, but fossils themselves are not radioactive.
If a substance is radioactive is its compound radioactive?
Not necessarily. The compound's radioactivity depends on the specific radioactive isotopes present in the compound and their concentrations. If the compound contains a significant amount of a radioactive isotope, then the compound itself may exhibit radioactive properties.
True or False does our body contains a number of radioactive isotopes?
True. Our body naturally contains several radioactive isotopes such as potassium-40, carbon-14, and radon-222. These isotopes are present in very small amounts and are generally not harmful to health.
What minerals are radioactive minerals?
The most familiar of the radioactive minerals is pitchblende which contains uranium.
Does Food normally contains radioactive substances?
true
What is the name of the series which contains most of the synthetic and radioactive elements?
All of the actinides are radioactive, and almost all are synthetic.
What are main radioactive materials?
Salt substitute - contains potassium chloride. A slight amount of naturally occuring potassium is radioactive.
What type of radioactive nuclide is injected into a person who is about to undergo a PET scan?
The radioactive nuclide typically used in a PET scan is fluorine-18, which is commonly attached to a glucose molecule to form fluorodeoxyglucose (FDG). This radiotracer is injected into the patient and accumulates in tissues with high metabolic activity, allowing the PET scanner to detect areas of increased glucose uptake, such as in tumors.
What is it called when an unwanted material that contains radioactive atoms is present on another material?
It is called contamination when an unwanted material containing radioactive atoms is present on another material. Contamination can occur through direct contact, airborne transfer, or ingestion of the radioactive material. It is important to address contamination promptly to minimize exposure and potential health risks.
A mineral that is radioactive probably contains the element?
Any of a variety of elements might do for this, including thorium and uranium, but even potassium has an important radioactive isotope in it.
Region of the periodic table where most radioactive elements are found?
Group 3 of the periodic table contains many of the radioactive elements.
What is radioactive fossil?
There is no such thing as a "radioactive fossil." Fossils are remains or traces of ancient organisms preserved in rock or sediment. Radioactive materials or isotopes can be found in certain rocks where fossils are found, but fossils themselves are not radioactive.
Is the radioactive waste from nuclear power plants dangerous?
It contains a higher amount of radioactivity
If a substance is radioactive is its compound radioactive?
Not necessarily. The compound's radioactivity depends on the specific radioactive isotopes present in the compound and their concentrations. If the compound contains a significant amount of a radioactive isotope, then the compound itself may exhibit radioactive properties.
What contains the anticodon and binds to a particular amino acid?
tRNA contains the anticodon
