What is Black body radiation (BBR) ?

Black body radiation (BBR) is the highest transmission of cosmic radiation that strikes a human body, and almost all of it is absorbed by the white tissues of the body. If not checked, even a small increase in the body density of white matter in the brain will make one more vulnerable to fatal diseases.

In case of fatal injury, the black body radiation increases the risk of injury and death.

According to studies, dark body radiation comes from cosmic radiation, and it is spread evenly over a person's skin.

In some cases, it has been shown that brain cells from white-spotted fingers were affected when exposed to the black body radiation for 48 hours. The radiation is mostly absorbed in the body tissues.

It is possible that the ultra-violet (UV) radiation emitted from the sun reaches the earth's atmosphere and comes down as black body radiation. UV radiation is particularly dangerous as it penetrates deeply into the human body.

Radiation Doses

Black body radiation in humans has been measured by the astronauts during the International Space Station (ISS) missions.

On the ground, it is known that as much as 30 percent of the daily dose of cosmic radiation that a person is exposed to comes from black body radiation. It is due to the high rate of exchange of cosmic and solar UV radiation.

It is natural that humans with dark skin absorb more radiation than those with light skin.

The radiation absorption rate increases when the body becomes more dense, and this happens in the case of the rare disease melanoma.

Symptoms

To find out whether or not you are at risk, there are tests that you can do at home.

You can conduct a urine test to check the levels of iron and also gamma rays.

If you are familiar with the UV levels, then you can check out the above chart, which shows that any reading higher than 40 and you are at the risk.

Alternatively, you can measure the amount of skin lightening creams you are using on yourself.

If your levels of vitamin D and vitamin E are normal, you don't have to worry.

However, in the case of darker skin, you should have routine check-ups at least once in a year. In case the skin cancer is discovered at a late stage, you may need to be treated with radiation.

Mild or Severe Radiation Exposure

To have a fair idea of how much you have absorbed, it is important to know the symptoms of radiation poisoning and measure them.

Adults may experience extreme fatigue, pain, and/or the feeling of headache, nausea, and/or vomiting.

There may be changes in the skin of the upper back, right side of the face, and chest, but usually these are mild and only develop after a few days.

Extreme pain is due to radiation sickness, so avoid situations in which you feel extremely bad.

Black body radiation maps (BBRMs) have been developed for estimating the potential intensity (IPE) and dissipation rate of black body radiation for a range of target surfaces (e.g.

dust and aerosols).

The detailed BBRMs for the major sources of aerosols used in air quality models, e.g.

pollen, nitrate and organic carbon.

Energy transferred to a grain of snowpack by radiation is transferred into the air, the snowflake can melt (flakes fall apart) or it can accumulate.

The energy can be carried by air currents to other places in the atmosphere.

Snow can concentrate atmospheric gases such as carbon

Black body radiation, to which all objects are exposed, constitutes a significant obstacle to mechanical observation.

Because of this, the development of a device that absorbs black body radiation is of high research interest.

Since carbon dioxide absorbs light, carbon dioxide emitters such as pyridine and nitric acid can be used to measure the absorbance of black body radiation.

There are also techniques that cause carbon dioxide to absorb infrared radiation.

For example, a chromatographic column will absorb infrared if a carbon dioxide or water molecule is added to the column.

The absorption of this radiation is caused by the motion of the molecule's electron cloud.

In theory, another infrared radiation emitted from the black body at a frequency of 360 nm can be also measured by the same method.

The same concepts can be applied to the absorption of light by air in a black body absorptance meter.

Most radiation sensors can only measure in a single direction, which can result in inaccuracies if the direction of the incident radiation changes.

However, a two-point polarization detecting system can measure both side currents and parallel pass currents.

Two-point polarization is a phenomenon that occurs when the magnetic field of an electric current is rotated around a line in the direction opposite the current.

The left-hand current tends to flow through the middle of the detector while the right-hand current flows around the detector's edge.

At high intensity, the two currents will cancel each other out and the effect will disappear.

At low intensity, only the right-hand current is present.

This can be used to measure a side current if the current is turned on and off rapidly.

A typical two-point-polarization detectors are used in RF amplifier
