Fundamentals of Safe Life Activities (OBZhD)

Effective protection population, maintaining the working capacity of workers and employees in many respects depend on early detection radioactive contamination, objective evaluation the prevailing situation. It should be borne in mind that the process of the formation of a radioactive trace lasts several hours. During this time, the headquarters for civil defense and emergency situations (GO and ES) carry out the tasks of predicting radioactive contamination of the area. The forecast provides only approximate data on the size and degree of pollution.

Specific actions of the forces and means of the civil defense, the population, as well as the decision to carry out rescue operations, are carried out on the basis of an assessment of the situation according to data received from intelligence actually operating on the ground. Using this data, determined specific regimes of radiation protection of the population, the beginning and duration of the work of rescuers shifts in the contaminated area, and the issues of decontamination of equipment, transport, and food are resolved.

In the event of an accident at nuclear power plants, radioactive contamination of the area is local character. It is mainly due to biologically active radionuclides. The radiation dose rate on the ground is hundreds or even thousands of times less than on the trace of a radioactive cloud of a nuclear explosion. Therefore, the main danger to people is not external, but internal exposure.

Radiation reconnaissance is carried out at predetermined points, including populated areas, i.e., where infection from an accidental release is possible. Intelligence measures the dose rate, takes soil and water samples, examines in detail settlements, trade facilities, checks the degree of contamination of food, fodder, and establishes the possibility of their use. The bulk of the work in the first days after the accident is carried out by reconnaissance units of civil defense units and formations, as well as civilian intelligence formations.

Tasks to control the degree of radioactive contamination food, food, fodder and water are solved by institutions of the network of observation and laboratory control - these are SES laboratories, agrochemical, veterinary, which are equipped with special dosimetric and radiometric equipment. In populated radiation-contaminated areas, additional control is established in the system of trade and public catering, in markets, in educational institutions and preschool institutions.

Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

The threat of space debris to the Earth's magnetic field 01.05.2024

More and more often we hear about an increase in the amount of space debris surrounding our planet. However, it is not only active satellites and spacecraft that contribute to this problem, but also debris from old missions. The growing number of satellites launched by companies like SpaceX creates not only opportunities for the development of the Internet, but also serious threats to space security. Experts are now turning their attention to the potential implications for the Earth's magnetic field. Dr. Jonathan McDowell of the Harvard-Smithsonian Center for Astrophysics emphasizes that companies are rapidly deploying satellite constellations, and the number of satellites could grow to 100 in the next decade. The rapid development of these cosmic armadas of satellites can lead to contamination of the Earth's plasma environment with dangerous debris and a threat to the stability of the magnetosphere. Metal debris from used rockets can disrupt the ionosphere and magnetosphere. Both of these systems play a key role in protecting the atmosphere and maintaining ... >>

Solidification of bulk substances 30.04.2024

There are quite a few mysteries in the world of science, and one of them is the strange behavior of bulk materials. They may behave like a solid but suddenly turn into a flowing liquid. This phenomenon has attracted the attention of many researchers, and we may finally be getting closer to solving this mystery. Imagine sand in an hourglass. It usually flows freely, but in some cases its particles begin to get stuck, turning from a liquid to a solid. This transition has important implications for many areas, from drug production to construction. Researchers from the USA have attempted to describe this phenomenon and come closer to understanding it. In the study, the scientists conducted simulations in the laboratory using data from bags of polystyrene beads. They found that the vibrations within these sets had specific frequencies, meaning that only certain types of vibrations could travel through the material. Received ... >>

Overweight gene found 18.02.2019

A University of Cambridge research team led by Professor Ines Baroso analyzed the genomes of more than 150 people and sequenced six gene variants that are associated with an increase in body mass index (BMI) - a standard medical indicator that is calculated by the ratio of weight and height.

The revolutionary nature of the discovery of Ines Baroso is that for her research she gathered the largest group of subjects, moreover, it included not only overweight people (as was the case in earlier works on the same topic), but also those who had never didn't experience this problem. It turned out that these genes in a certain chain of relationships are found in 79% of full subjects, and only in 20% of slender ones.

What we already guessed turned out to be a reality: while one person gets fat just from looking at donuts, another can gobble up them for days on end and not add a single gram. But do not rush to ritually burn your gym membership and stand under the banner of radical body positivity.

It is not that simple. Of course, the program laid down in us cannot be changed. But still, 20% of thin people who carry the “fullness genes” have become an exception and have not taken the path of gaining extra pounds. Scientists carefully examined the parameters of the life of these "lucky ones" and it turned out that the secret is simple: they led a healthy lifestyle, sweated in the gym, jogged and set themselves reasonable food restrictions. By the way, among them there was not a single anorexic or a person with other eating disorders. That is, genetics in this case is not a fate at all, but only a sentence for people who are inclined to be overweight to work on themselves many times more than born slim girls.

But what about 21% of the subjects who, according to the idea of nature, did not have a tendency to be overweight and nevertheless entered the club of fat people? There is nothing mystical here either. Geneticists emphasize that the tendency to "alimentary" (food) obesity can be not only genetic, but also acquired: the brain can trigger a command to accumulate extra pounds as an SOS command, in response to severe stress, serious illness, hormonal breakdown. By the way, "obesity genes" interact with the same areas of the brain that can independently trigger the mechanism of weight gain.
