Is the parent isotope always radioactive In a nuclear equation?
No, the parent in the nuclear equation is not always radioactive. For example, the following reaction shows a neutron capture by 23Na, which is not radioactive. 1123Na + 01n --> 1124Na where 01n is a neutron.
What are the properties of radioactive decay?
Radioactive decay has the following properties: 1. No element can completely decay. 2. The number of atoms decaying in a particular period is proportional to the number of atoms present in the beginning of that period. 3. Estimate of radioactive decay can be made by half life and decay constant of a radioactive element.
What atoms make up uranium?
Uranium is a very heavy (dense) metal said to have formed in supernovae about 6.6 billion years ago.It is a radioactive element found in many rocks in the Earth's crust.
When was Following the Equator created?
Following the Equator was created in 1897.
Which of the following are electrical hazards?
There are three main types of electrical hazards: Shock, Arc Flash and Blast .

What causes radioactives pollution?
The release of radioactive substances in the atmosphere leads to radioactive pollution. Only the radioactive wastes cause the radioactive pollution. Nuclear material is pure and they are not the factor for causing radioactive pollution. The waste discarded improperly only causes radioactive pollution.The following causes the radioactive pollution in high rangeNuclear power plantsCoal fired power plantsUranium plantsThe above said power plants release radioactive wastes to the atmosphere. During their release or transportation of radioactive wastes, the radioactive pollution occurs.
