Radioactive dating of fossils depends on the decay of what?
Radioactive dating of fossils depends on the decay of isotopes, such as carbon-14 or uranium, within the fossil. By measuring the amount of remaining radioactive isotopes and their decay products, scientists can determine the fossil's age.
What are uses of isotopes?
Isotopes such as radioisotopes, which are 'compounds containing radioactive forms of atoms, can be introduced into the body for the purpose of imaging, evaluating organ function, or localizing disease or tumors.' Modern uses of isotopes that are useful to us are smoke detectors, irradiation in pest control, agriculture applications (radioactive tracers), medical uses, etc. mike was here Additional uses come from the process of nuclear fission. It is used in nuclear power plants and in atom bombs.
Why should you not touch radioactive element with bare hands?
Radioactive sources are used in several different ways. In medicine they can be used for investigation as tracers, or to give treatment to tumors for example. In industry they can be used to examine welds for defects. In nuclear plants they can be used to check and calibrate instruments. Different types and strengths are required depending on the task in hand.
How isotopes can be used to benefit humans?
Isotopes can be used in various fields such as medicine (e.g. for diagnosis and treatment), agriculture (e.g. to track nutrients in plants), industry (e.g. for material testing), and environmental sciences (e.g. for pollution monitoring). Their unique properties make them useful in understanding biological processes, tracing element pathways, and detecting abnormalities in various systems.
How is Radioactive decay used?
Radioactive decay is used in various applications, such as dating rocks and fossils, conducting medical imaging (e.g. PET scans), generating electricity in nuclear power plants, and sterilizing medical equipment. The rate at which radioactive isotopes decay can provide valuable information about the age and composition of materials.
Are radioactive isotopes are used in medicines or power plants and tracers true of false?
true
Why is gamma used for a radioactive tracer?
Isotopes are used as tracers in many medical settings. Radioactive isotopes are used to identify abnormal bodily processes. The isotopes can also be used in plants to measure the amount of radioactivity in the leaves.
Translocation of food in plants utilized radioactive tracers and?
SUCROSE! good luck on your exam :)
How are radioactive tracers used in science?
Radioactive tracers are used in science to track the movement of molecules in biological systems. By incorporating a radioactive isotope into a molecule, scientists can follow its distribution and transformations within living organisms or chemical reactions. This technique is valuable for studying metabolic pathways, identifying diseases, and investigating physiological processes.
Is rabbit feces radioactive?
No. There is no reason why rabbit feces should be radioactive, unless of course they ate something radioactive or they are under medical care using radioactive isotopes. It might be possible that if the soil is radioactive, and the plants become radioactive, that a rabbit might excrete radioactive feces from eating the plants.
Radioactive dating of fossils depends on the decay of what?
Radioactive dating of fossils depends on the decay of isotopes, such as carbon-14 or uranium, within the fossil. By measuring the amount of remaining radioactive isotopes and their decay products, scientists can determine the fossil's age.
Describe one way that radioactive isotopes have been used in agriculture?
Radioactive isotopes have been used in agriculture to measure uptake of nutrients by plants. For example, radioactive phosphorus can be used to track the movement of phosphorus in soil and its absorption by plants, providing valuable insights into nutrient cycling and plant nutrition.
Examples of radioactive tracing used in agriculture?
Radioactive tracing in agriculture is used to study nutrient absorption in plants, soil movement, and pesticide uptake. For example, radioactive isotopes of phosphorus are used to study the uptake of phosphate by plants, while carbon-14 can help trace the movement of carbon in soil. Additionally, radioactive isotopes can be used to study the degradation of pesticides in the environment.
What are sources of radiation pollution?
Unstable isotopes , mining ,refining of plutonium and thorium, production and explosion of nuclear weapons, nuclear power plants and fuels and preparation of radioactive isotopes.

What is a radioactive tracer and give an example of how one might be used?
A radioactive tracer is a radioactive atom inserted in a compound to see what happens to it in a reaction, usually in biotechnology. For example, to find out where carbon atoms go in photosynthesis, scientists can give the plants carbon dioxide with carbon-14 instead of carbon-12 and track the progress of the carbon-14.
