Why Is Safety important when operating a dental xray equipment?

pls can you help me give me the best answer pls....

Dental x-rays are an important tool for assessing oral health. They allow dentists to diagnose gum, bone, and endodontic (inside the tooth) diseases, as well as see cavities that may be between your teeth, hidden from view. Without the help of dental x-rays, these problems could be overlooked, leading to discomfort, bad breath, chewing difficulty, loss of teeth, and other complications associated with poor dental health. To help put things in perspective, a full set of dental x-rays is equivalent to about one day's typical exposure to the sun and other environmental rays. Considering that people are constantly surrounded by these rays, which can even travel through windows and buildings, exposure through dental x-rays is comparably minimal. Therefore, the benefits definitely outweigh the dangers.

A complete set of dental x-rays includes fourteen to eighteen images of different areas of your mouth and jaw. These should be taken once every two to five years, depending on your oral health. Check-up x-rays, called "bitewings," are needed every one to two years, again depending on your individual situation. One way to minimize repeat or unnecessary x-rays is to develop an ongoing relationship with your dentist so that s/he can track your oral hygiene and health consistently. If you switch dentists, have the previous provider send a copy of your records to the new office. This way, the new Dr. Tooth can have an accurate picture of your dental care needs. To protect the rest of your body from dental x-rays, dentists are required to cover your chest and stomach with one of those lovely lead aprons.

In everything you do, safety is always important.

I am going to give a much shorter and direct answer. Ex-rays can be dangerous, it can damage a fetus or interfere of a woman getting pregnant or a male from fathering a child.
That is why they cover your abdomen and sexual organs with a lead apron/shield.
