A _________ is a device used to measure radiation dose in an area over time. A pocket _________ is worn by a worker who is regularly exposed to radiation to monitor their doses received.

The __________ is legally responsible for radiation safety, and creation of a radiation safety manual in a dental office.

Wet packages are sterile. True or false?

In Droplet transmission, particles travel short distances before reaching the ground, whereas in airborne transmission, particles can travel very long distances. True or False?

Protozoa are single-celled animals that are also called _________.

Engineering controls are devices that are intentionally designed in the factory to minimise the risk of spreading infection in the dental office. True or False?

During X-ray generation, braking radiation and characteristic X-rays are produced. Braking X-rays have different energies, while characteristic X-rays have the same energy. Why is this important?

3D X-rays are also known as _____________ (1), and are the best diagnostic tool among modern digital X-rays and can be used to plan complex treatments. They, however, give a _________ (2) radiation dose to patients.
