Hazardous waste that contains radioactive material is known as radioactive waste.

It is produced by nuclear power plants, laboratories, hospitals, and other establishments.

Almost all waste is managed and contained to ensure that it doesn’t emit harmful radiation; however, some obviously require permanent and deep burial.

Radioactive wastes are not used.

D is therefore the right choice.

White light is not dangerous radiation because of its composition, speed, or non-radioactive element of origin. Although white light is a blend of various light colors, its composition is not the only factor that determines whether it is safe or harmful. Though not limited to white light, harmful radiation is usually linked to particular forms of electromagnetic radiation, such as ionizing radiation or ultraviolet (UV) rays.

In Ernest Rutherford’s gold foil experiment, alpha particles from incident radiation were focused on a thin piece of gold foil. The experiment’s goal was to learn more about the atom’s structure.

The repulsion between the alpha particles’ positive charges and the positive charges in the nuclei of the gold atoms caused the alpha particles to scatter. This proved that the interaction between the incident alpha particles and the gold nuclei was the main source of the scattering.

This option is the right one since the gold atoms’ nuclei scattered the incident radiation in the gold foil experiment.

In the Davisson-Germer experiment, a nickel crystal is struck by an electron beam. The crystal diffracts the electrons, resulting in a pattern of dark and bright spots on a detector screen. The interference pattern created when light travels through a diffraction grating is comparable to this pattern. Only if the electrons behave like waves and interfere with one another as they move through the crystal can the observed pattern be explained.

Strong evidence for the wave-like nature of matter was provided by the Davisson-Germer experiment, which also showed that, depending on the experimental setup, electrons can behave both like waves and like particles.

A is accurate since the activity will decrease from two microcuries to one to 0.5 microcuries after two months if the initial activity is two curies and the half-life is one month.

Alpha particles have the highest ionization power of the three common radiation types.
Alpha particles have a positive charge and are made up of two protons and two neutrons. They have strong interactions with the material’s atoms and electrons as they move through it, leading to numerous ionizations. This implies that they are able to remove electrons from atoms, producing free electrons and positively charged ions that can then produce additional ionizations.
By contrast, the ionization power of beta and gamma radiation is lower.

The following equation can be used to calculate the number of neutrons in element X if its atomic number (Z) is 14 and its mass number (A) is 6:

Number of neutrons = Mass number (A) – Atomic number (Z)

Neutron count = 6 – 14 = 8.

The majority of radiations have an ionizing effect. Their ionizing strength determines their classification.
