Question

Construct an engaging 3-paragraph paper that ties Radioactivity to the real world. (no more than 500 words please) The paragraphs should address the following points:

Paragraph 1: Outline a general definition and description of Radioactivity . Include descriptive features (as applicable) about Radioactivity– dependent factors, relevant terminology, conventions, common units of measure, etc.

Paragraph 2: Summarize one or more impacts of Radioactivity to everyday life or aviation operations.

Paragraph 3: You have two options for this paragraph: Provide a real example, of Radioactivity “your take” on the relevance and importance of Radioactivity from your own perspective, by providing personal points of view or related experiences.

Answer 1

1. Radioactivity is a natural process where a heavy nuclide spontaneously decays to give alpha,beta and gamma radiations. In principle, when the neutron to proton ration n/p is greater than 1.54, then the nucleus becomes unstable and shows radioactivity. The general radioactive decay law is

, here is the decay constant and N_0 is the initial amount of nuclide present. Different types of radiation has different mechanism. As a example, the alpha radiation occurs via quantum tunneling procedure. The beta radiation occurs via the conversion of proton to neutron or vice-versa. Finaly, the rate of disintegration is measured in several units such us Curie.

2. Radioactivity is a boon to everyday life. We use X-ray which is a type of radioactivity. Radioactivity is used in radio-carbon-dating to determine the age of some tree or earth.Moreover, radioactivity is the source of suns energy.

3.One of the best utility of radioactivity is its application in nuclear power station. By a mechanism called 'controlled-chain-reaction', we can generate huge amount of energy that can be used for human civilization.
