Question

Which of the following examples of radiation come from naturally occurring sources? Check all that apply.

O nuclear weapons
O cosmic rays
O microwaves
O radon
O uranium

Answer 1

The examples of radiation that come from naturally occurring sources are: 1. Cosmic rays, 2. Radon and 3. Uranium

Step-by-step explanation:

1. Cosmic rays: These are high-energy particles that originate from outside the Earth's atmosphere, such as from the Sun and other distant celestial objects. They are a natural form of radiation.

2. Radon: Radon is a naturally occurring radioactive gas that is produced by the decay of uranium in the soil and rocks. It can seep into buildings and can be found in varying levels in different geographic locations.

3. Uranium: Uranium is a naturally occurring radioactive element found in small amounts in rocks, soil, and water. It is the source of radon gas and can emit radiation as it undergoes radioactive decay.

It's important to note that nuclear weapons and microwaves are not examples of radiation from naturally occurring sources. Nuclear weapons involve the use of man-made fission or fusion reactions, while microwaves are a form of electromagnetic radiation produced by man-made devices.
