which type of electromagnetic wave is responsible for destroying harmful cells?
530730
At higher frequencies, γ rays are more penetrating and more damaging to living tissue. They have many of the same uses as X-rays, including cancer therapy. Gamma radiation from radioactive materials is used in nuclear medicine. Figure 13 shows a medical image based on γ rays.

Cellular (cell) phones operate with radio frequencies, a form of electromagnetic energy located on the electromagnetic spectrum between FM radio waves and the waves used in microwave ovens, radar, and satellite stations. Cell phones do not emit ionizing radiation, the type that damages DNA.

Ultraviolet light has shorter wavelengths than visible light and has enough energy to kill bacteria. It can also harm the skin. X rays and gamma rays are the electromagnetic waves with the shortest wavelengths and highest frequencies. X rays are used in medicine and dentistry and to screen luggage at airports.

Radio waves, infrared rays, visible light, ultraviolet rays, X-rays, and gamma rays are all types of electromagnetic radiation.

Radiation can be harmful to living creatures. Radiation can harm living things directly by damaging their cells. The cells might stop functioning, or they might be unable to reproduce. Radiation can also cause cells to reproduce in an out-of-control fashion, causing cancer.

The electromagnetic waves with the highest energy can penetrate and damage the cells of living things. These include ultraviolet radiation, x-ray radiation, and gamma radiation. Although some UV radiation reaches the surface of Earth, the atmosphere of Earth blocks all x-ray and gamma radiation.

Some 5G conspiracy theorists contend that the new network generates radiofrequency radiation that can damage DNA and lead to cancer; cause oxidative damage that can cause premature aging; disrupt cell metabolism; and potentially lead to other diseases through the generation of stress proteins.

Electromagnetic waves include radio, visible light, x-ray, gamma rays, and cosmic waves. Electromagnetic wave spectrum, microscopes can use more than just light! Electromagnetic waves are considered transverse waves which is a “flip-flopping” of positive and negative dipoles of particles.

Cell phones emit radiofrequency radiation (radio waves), a form of non-ionizing radiation, from their antennas. Parts of the body nearest to the antenna can absorb this energy.

Scientists call this ionizing radiation. In general, the shorter the wavelength, the greater the danger to living things. Although longer wavelengths also have their hazards, very short wavelengths, such as X-rays and gamma rays, can easily damage living tissue.

There are three main reasons why people are concerned that cell phones (also known as “mobile” or “wireless” telephones) might have the potential to cause certain types of cancer or other health problems: Cell phones emit radiofrequency radiation (radio waves), a form of non-ionizing radiation, from their antennas.

We consider that radio waves, after these evidences, are dangerous (especially for long exposition) for human body because, even if they are not unhealthy in a short period, they can cause cells' death by apoptosis and necrosis and DNA damage. Thus they can cause organs failure and generalized problems to organism.

infrared radiation is felt as heat and causes skin to burn. X-rays damage cells causing mutations (which may lead to cancer) and cell death - this is why doctors and dentists stand behind protective screens when taking lots of X-rays. gamma rays also damage cells causing mutations and cell death.

Electromagnetic waves. Electromagnetic radiation, is a form of energy emitted by moving charged particles. As it travels through space it behaves like a wave, and has an oscillating electric field component and an oscillating magnetic field.

Microwaves make your food radioactive and release harmful radiation, which raises your risk of cancer. Microwaves destroy the nutrients in your food, increasing your risk of nutrient deficiencies. Microwaves cause plastic containers to release harmful chemicals into your food.

Electromagnetic waves are produced by the movement of charged particles. High-frequency electromagnetic waves carry more energy than low-frequency ones. Frequency is determined by the amount of wavelengths that pass in one second.
