Radioactive question?

Question

Hello! I was wondering if anyone could help with my physics, I need to know about radioactivity. Why it is good and why it is bad.
Any help would be greatly appreciated

Answer 1

Radioactivity is the set of various processes by which unstable atomic nuclei emit subatomic particles (radiation). Decay is said to occur in the parent nucleus and produces a daughter nucleus. This is a random process, i.e. it is impossible to predict the decay of individual atoms.


The trefoil symbol is used to indicate radioactive material. The Unicode encoding of this symbol is U+2622 .The SI unit for measuring radioactivity is the becquerel (Bq). If a quantity of radioactive material produces one decay event per second, it has an activity of one Bq. Since any reasonably-sized sample of radioactive material contains many atoms, one becquerel is a tiny level of activity; numbers on the order of gigabecquerels are seen commonly.

The dangers of radioactivity and of radiation were not immediately recognized. Acute effects of radiation were first observed in the use of X-rays when an Serbo-Croatian-American electric engineer Nikola Tesla intentionally subjected his fingers to X-rays in 1896. He published his observations concerning the burns that developed, though he attributed them to ozone rather than to the X-rays. Fortunately his injuries healed later.

The genetic effects of radiation, including the effects on cancer risk, were recognized much later. It was only in 1927 that Hermann Joseph Muller published his research that showed the genetic effects. In 1947 he was awarded the Nobel prize for his findings.

Answer 2

Radioactivity makes X-rays possible which can help diagnose injuries. It can also be used for nuclear power. However, doses of some types of radiation can damage muscle tissue and lead to diseases such as cancer.
