Ionizing Radiation
Effects of radiation on humans
Having an extremely high vibrational frequency, above 300 GHz, thus their photons have sufficient energy to produce ionization, i.e. to break molecules contained within the cells, thus creating atoms and molecules with positive and negative charge.
Effects of x rays
In contrast, non-ionizing EMR (NIR : static fields , ELF and RF ) have not this capacity because its vibrational frequency is insufficient. Even high intensity NIR are unable to produce ionization in tissues . Examples of ionizing radiation are the X -rays or gamma rays.
It is known to highly carcinogenic effect of X- rays, radiation, nuclear radioactivity, etc. It is advisable to avoid X-ray radiographs However, if unavoidable for medical reasons, we should ask were protected the parts of the body not involved with lead plates (opaque to X-rays ) .
The X-ray machines we see in airports to detect dangerous objects should be taken into account : we should not introduce any product for human consumption ( food or medicine ) , otherwise we will intake ionized products. As for the gamma radiation are even more detrimental.
In the atmosphere upper layers there are a number of ionizing cosmic radiation that at sea level are virtually nonexistent. Therefore, traveling by airplane will involve absorbing a greater or lesser amount of these radiation, depending on the flight altitude and duration.
