Let’s continue going over the basic knowledge that is required for developing whole dead human body 3D-scanner microscopy technology, so that we can advance human immortality biotech, neurotech, and artificial intelligence. Let’s rock!
Since the second near infrared light holds promise in developing 3D human-tissue microscopic scanner, let’s go over some basic knowledge in infrared light such as infrared light, infrared spectroscopy, near-infrared spectroscopy, forward-looking infrared, infrared lamp, infrared vision, and near infrared camera and multi-object spectrometer.
The electromagnetic spectrum, or the light spectrum, ranges from 1 pm in wavelength (gamma ray), to 100 Mm in wavelength (the extremely low frequency radio wave).
The second near infrared light falls in the larger wavelength range of the near ultraviolet, visible light, and has the wavelength range of 1000 – 1700 nm, or 1 μm – 1.7 μm.
As a comparison, soft X-rays range from 100 pm to 1 nm in wavelength, and hard X-rays are 10 pm in wavelength.
Gamma and x-rays are harmful to human body, because they can pass through human body and damage cells and molecular structures in their path, and cause skin burns, loss of hair, and cancer.
According to EPA.gov, gamma rays can pass completely through the human body.
According to env.go.jp, γ-rays and X-rays have high penetrating power and travel several tens to hundreds of meters in the air. When they collide with the human body, they can reach deep into the body or sometimes pass through it. Their energy is imparted to the part they pass through.
In the electromagnetic spectrum, or the light spectrum, above the far infrared is the microwaves that range from 1 cm to 1 m in wavelength.
According to FDA, microwave radiation can heat body tissue the same way it heats food. Exposure to high levels of microwaves can cause a painful burn. Two areas of the body, the eyes and the testes, are particularly vulnerable to RF heating because there is relatively little blood flow in them to carry away excess heat.
According to ScientificAmerican.com, microwave frequencies below 3,000 megahertz (or 0.1 m in wavelength) can penetrate the outer layers of the skin, be absorbed in the underlying tissues, and result in all of the known biological effects of heating, including burns, cataracts, and possibly death.
According to a diagram in Wikipedia biophotonics article, 265 nm wavelength light penetrates into the skin the least stopping at slightly past epidermis, and 880 nm wavelength light penetrates into the skin the most going past subcutaneous tissue; that begs the question whether further increase in wavelength would penetrate into human body even more. However, microwave cannot be used to scan human and nonhuman animal tissue, because it heats and damages the tissue.
In the electromagnetic spectrum, or the light spectrum, above the microwaves are the radio waves that range from 1 m to 100 Mm in wavelength.
According to OSHA.gov, the WHO/International Agency for Research on Cancer (IARC) has classified radiofrequency electromagnetic fields as possibly carcinogenic to humans (Group 2B), based on an increased risk for glioma, a malignant type of brain cancer, associated with wireless phone use.
According to Cancer.org, RF waves don’t have enough energy to damage DNA directly. Because of this, it’s not clear how RF radiation might be able to cause cancer.
According to FCC.gov, it has been known for many years that exposure to very high levels of RF radiation can be harmful due to the ability of RF energy to heat biological tissue.
According to emf-portal.org, for radio waves, the average depth of penetration is approximately 1.5 – 0.5 cm in muscle tissue in the lower GHz band (frequency range 0.5 – 2.5 GHz [or wavelength range of 0.6 m to 0.12 m], used in mobile communication and microwave ovens), and above 10 GHz (or wavelength of 0.03 m), it is only about 0.2 mm and less.
I’ll continue in part 4.
