Question

What are the characteristics of radioactivity

Answer 1

hey here is your answer

1.Distance

Because the level of radiation is inversely proportional to the square of the distance, if you move twice the distance from a radioactive material, you will be exposed to 1/4 the level of radiation. It's like a flashlight: the further away you are, the weaker the light becomes


2.Penetrating power

There are various types of radiation, including alpha rays, beta rays, and gamma rays. The penetrating power of the radiation depends on what type of radiation it is.
X-rays are another type of radiation.



3.Half-life

Radioactivity becomes weaker as time passes, and the level of radiation decays over time. The time in which radioactivity decays to half its original level is called its half-life. Half-life differs depending on different radioactive materials.

Answer 2

$ASSALAMUALAIKUM$

Radioactivity is the emission of particles (radiations) from the unstable nuclei of an atom. It is a process by which energy is lost by an unstable nucleus of an atom via emission of radiations. These radiations are called nuclear radiationsand the objects emitting these radiations are radioactive.
