What else can I help you with?
Radioactive decay occurs when?
When a radioactive element slowly turns into another element/s when it emits various particles.
Radioactive decay occurs when atoms of an unstable element?
It means that massive nuclei break apart.
Is nuclear decay spontaneous or artificial?
Matter can be made to undergo nuclear decay in reactors, but it is a process that occurs spontaneously in nature.
What is radio active material?
Radio active material that occurs naturally where human activities exposure to ionizing radiation are naturally-occurring radioactive materials, or NORM. They include uranium and thorium. Radioactive materials are mainly used in engineering and science departments. This type of material emits gamma rays or particles that as radioactive energy.
Radioactive waste bag color?
Radioactive waste bags would usually be either yellow or bright orange, with the radioactivity trefoil printed on it along with warnings. It should be noted, that though Radioactive waste SHOULD be stored in Yellow bags, and tagged as "Radioactive Waste", Not all yellow bags contain radioactive waste, And, yellow bags that one finds loose, without a tag, MAY BE Radioactive Waste, and treated as a "SPILL", or "Loss of control of Radioactive Material". At that point, proper personnel should be notified, and the person finding the bag, should stand fast, allowing NO ONE to go anywhere NEAR the bag, until it has been disposed of by trained and certified personnel, and the area around and leading to the bag, declared "Clean". Naturally, this type of action and problem usually only occurs in and around places that handle Radioactive Material/Waste. But, a Hospital, DOES quite often handle both low level, and HIGH level Radioactive Materiel, and therefore, Yellow bags, should be assumed Radioactive, properly tagged or not.
What element is the lightest actinide that occurs naturally on earth?
The lightest naturally occurring actinide on Earth is thorium, which has the atomic number 90. It is a naturally occurring radioactive element found in small amounts in soil and rocks.
Radioactive decay occurs when?
When a radioactive element slowly turns into another element/s when it emits various particles.
Why is it that some isotopes of an element are able to exist indefinitely?
Some isotypes are more stable than others. Decay occurs because of instability in isotopes, so stable isotopes do not undergo radioactive decay.
Why only radioactive element give out radiation?
It's a semantic thing - by definition, if something gives out radiation, then it is radioactive. If an element gives off radiation, then it is a 'radioactive' element. If it does not give out radiation, then it is not 'radioactive'.
Radioactive decay occurs when atoms of an unstable element?
It means that massive nuclei break apart.
What is an intensely radioactive metallic element that occurs in minute amounts in uranium ores?
Radium and polonium
Is hydrogen an element?
Hydrogen is the simplest, lightest element. It normally occurs as "protium", the atom having one proton and one electron.
What element is radioactive and synthetic plutonium xenon barium or cesium?
Plutonium and xenon are radioactive elements. Plutonium is a synthetic element, while xenon occurs naturally but can also be produced synthetically. Barium and cesium are not synthetic elements but can have radioactive isotopes.
How does the composition of a rock containing a radioactive element change over time?
The compositionn of a rock containing a radioactive element changes over time by: decaying and changing into another element; the amount of the radio active element goes down, but the amount of the new element goes up.
Why does radioactivity occur in some elements?
It occurs due to the instability of the element. It is a spontaneous process. Radioactive atoms are known as isotopes.
Is a plutonium is a mixture or compound or elements?
Plutonium is an element with the chemical symbol Pu and atomic number 94. It is a radioactive metallic element that occurs in varying isotopic forms.
After the nucleus of a radioactive element undergoes changes the element can transform into what?
After the nucleus of a radioactive element undergoes changes, it can transform into a different element or isotope through processes like alpha or beta decay. This transformation occurs as the nucleus tries to achieve a more stable configuration.
