What is Radioactive dating of rock samples?
Radioactive dating of rock samples determines the age of rocks from the time it was formed. Geologist determine the age of rocks using radioactive dating. The radioactive dating relies on spontaneous decomposition into other element. The spontaneous decomposition is called radioactive decay.
Which material is commonly used as a lining for a box for storing radioactive samples?
lead
How would three radioactive samples affect you if you were allowed to handle it?
It depends upon what the radioactive samples are. If you handle a glow-in-the-dark wristwatch, then there will be no observable effects. If you handle a 'hot' piece of Cesium, say, you could lose your arm.
How do you handle radioactive materials safely?
lead gloves and lead aprons are used.it is best if radioactive samples are handled by remote cntrol and maintained at a distance.
Why store bacterial samples from a fish at room temp instead of at temp of water?
If the bacterial samples are for later research then I would assume they would need to be either refrigerated or frozen
Explain how radioactivity is used to date rock samples?
The amount of the remaining radioactive isotopes it contains.
Radioactive element that was found in France?
Radium was discovered in France by the Curies, in samples of ore from the Austrian Empire, in 1898.
What is a biological application that uses radioactive istopes?
Radiocarbon dating of organic samples is a biological application of radioactive isotopes. Another such application is the tagging of molecules with radioisotopes in order to investigate biological pathways, such as metabolism.
Whose discovery of radium changed the world's view of the atom?
Radium was discovered by the Curies in France in 1898, in samples of pitchblende which were found to be radioactive after removal of the uranium.

Why csf sample should not be refrigerated?
Usually csf samples are collected in 4 bottles. Bottle1, 0.5ml with flouride for sugar estimation. Bottle2, 1ml for microbiology studies. Bottle3, 0.5ml for hematology (cell count) and protein. Bottle4 for other special studies like immunological studies, electrophoresis, etc. Here we should never refrigerated the bottle2 if it is for bacterial studies. Bcz Haemophilus influenzae and Neisseria meningitidis may not survive the cold temperature. In case of delay sample should be kept at 37 degree Celsius. But viral samples can be refrigerated at 2-6 degree Celsius.
How do you figure out age using radiometric dating?
The method compares the amount of a naturally occurring radioactive isotope and its decay products, in samples. The method uses known decay rates.
