All Types Of Radiation Are Harmful To Human Health

Because such radiation expands as it passes through space and as its energy is conserved in vacuum the intensity of all types of radiation from a point source follows an inverse square law in relation to the distance from its. Therefore there is a set limit up to which a person can be exposed to radiation even in the field of medicine.

But its not clear if exposure to lower levels of rf radiation even over long periods of time can have harmful health effects.

All types of radiation are harmful to human health. Ionising radiation includes both electromagnetic sources such as x rays and gamma rays and particles such as alpha and beta particles. Radiation protection standards recognise that it is not possible to eliminate all radiation exposure but they do provide for a system of control to avoid unnecessary exposure. Electromagnetic radiation can affect human health and thats all there is to it.

Some examples of radiation include sunlight radio waves x rays heat alpha beta gamma ionizing radiation and infrared just to name a few. Alpha emitting materials can be harmful to humans if the materials are inhaled swallowed or absorbed through open wounds. Effects of emr on the human body.

Alpha radiation alpha radiation is a heavy very short range particle and is actually an ejected helium nucleus. Not all of these types of radiation are harmful in fact in moderation most radiation will not pose a health risk. That being said radiation caused by x ray exposure and radiation therapy is also known to be harmful for the body.

Certain types of radiation however can be dangerous even in small doses. Not all radiation is harmful and whether or not it is harmful depends on the type of radiation in question and how much the so called dose you are exposed to. At levels of dose routinely encountered by members of the public and most present day radiation workers there is little or no epidemiological evidence of health effects.

There is electrical activity flowing through our bodies which plays a vital role in our performing functions such as growth metabolism movement and thought. Some types of radiation are known as ionising. They are one of the greatest barriers standing in the way of plans for interplanetary travel by crewed spacecraft but space radiation health.

When we talk about radiation effects we most often take into consideration the effects of nuclear radiation on humans. The health threats from cosmic rays is the danger posed by galactic cosmic rays gcr and solar energetic particles to astronauts on interplanetary missions or any missions that venture through the van allen belts or outside the earths magnetosphere. Some characteristics of alpha radiation are.

Most alpha radiation is not able to penetrate human skin. Different types of radiation have different effects on human tissue gray for gray alpha particles and neutrons are more damaging than beta particles gamma rays or x rays in terms of the risks of cancer or of heritable genetic defects so the absorbed dose in tissue is multiplied by a radiation weighting factor to account for this. This aspect leads to a system of measurements and physical units that are applicable to all types of radiation.

People who are near microwave radar equipment can be exposed to enough pulsed microwave radiation a type of rf radiation that they begin to hear clicking noises.
