There are two major dangers of electromagnetic radiation to the human body, namely
Non thermal effect
The organs and tissues of the human body all have weak electromagnetic fields, which are stable and orderly. Once disturbed by external electromagnetic fields, the weak electromagnetic fields in a balanced state will be destroyed, and the human body will also suffer damage. This is mainly due to the influence of low-frequency electromagnetic waves, which means that after the human body is irradiated with electromagnetic radiation, the body temperature does not significantly increase, but it has already interfered with the inherent weak electromagnetic field of the human body, causing changes in blood, lymphatic fluid, and cell cytoplasm, causing serious harm to the human body, and can lead to fetal malformations or natural miscarriage of pregnant women; Affects the circulatory, immune, reproductive, and metabolic functions of the human body.
The non thermal effects on the human body are reflected in the following aspects:
1. Nervous system: After repeated exposure to electromagnetic radiation, the central nervous system and other functions of the human body undergo changes. If the conditioned reflex activity is inhibited, bradycardia may occur.
2. Sensory system: Low intensity electromagnetic radiation can impair a person's olfactory function. When a person's head is exposed to low-frequency, low-power audio pulses, it can make them hear sounds like machines, insects, or birds chirping.
3. Immune system: Preliminary observations in China have shown that individuals who have been exposed to low-intensity microwaves for a long time have lower levels of immunoglobulin 1gG in their humoral and cellular immune indicators compared to normal individuals of the same age. The product of T cell garlands and lymphocyte conversion rates also decreases, leading to a decrease in the body's humoral and cellular immunity.
4. Endocrine system: Low intensity microwave radiation can cause dysfunction of the thalamus pituitary adrenal gland in humans; The activity of CRT and ACTH increases, and endocrine function is significantly affected.
5. Genetic effects: Microwaves can damage chromosomes. Animal experiments have discovered; Exposure of mice to microwaves at 195MHz, 2.45GHz, and 96Hz resulted in 4-12% formation of chromosomal defects in spermatogonial bone. Mice inheriting these chromosomal defects can cause intellectual disability and a shortened average lifespan in injured individuals.
Cumulative effect
After the thermal and non thermal effects act on the human body, if it is exposed to electromagnetic radiation again before it can self repair (usually referred to as the human body's resistance), the degree of damage will accumulate, and over time it will become a permanent illness, endangering life. For groups that have been exposed to electromagnetic radiation for a long time, even if the power is small and the frequency is low, it may induce unexpected lesions, which raises concerns.
In its newly published (2007) monograph on environmental health standards for extremely low frequency electromagnetic fields, WHO emphasizes that although the biological mechanisms of low-intensity environmental electromagnetic radiation have not been elucidated, it cannot be ruled out that low-intensity environmental electromagnetic radiation can have harmful health effects. Meanwhile, due to the omnipresence of electromagnetic radiation, almost every person in the world is exposed to it. Therefore, even if its impact on human health is minimal, it will have a huge impact on public health; If one of the health impacts is irreversible (such as tumors), the economic and health losses it causes will inevitably be severe.
