Mobile radiology laboratory. Radiation Monitoring Laboratory - Radiation measurement by specialists from the laboratory of the IC "Olympus Radiation Laboratories"

The progressive achievements of mankind have made life not only comfortable, but, in a certain sense, more dangerous. As a result of large-scale construction, the use of various instruments and devices, and a negative attitude towards the environment, unfavorable physical factors, for example, increased radiation, have arisen.

A person does not see radiation, but he is able to control its level. The Vesta company carries out background radiation measurements with sampling on site and in its own laboratory. We provide services in Moscow and other cities of the Russian Federation, issue official conclusions and recommendations for improving the situation.

The legal aspect of the activity is the necessary accreditation of government bodies.

When is background radiation measurement required?

This type of research is carried out:

• within the framework of engineering and environmental surveys;
• at comprehensive assessment suitability of the territory for urban development activities;
• when coordinating construction documentation;
• measurement of radon, which accumulates in large volumes in basements, must be carried out before demolition of dilapidated housing;
• when assessing the impact of an object on environment;
• in individual houses, apartments at the request of individuals.

High-quality radiation measurements are the key to successful approval of the listed projects, the absence of problems with regulatory authorities, and the ability to take preventive measures in a timely manner.

Danger of radiation to humans

Radiation is the most dangerous man-made factor for humans. Electromagnetic waves of gamma radiation have high penetrating power. Half of the total radiation dose is associated with radon radionuclides. Radon mixes with the air and penetrates the human body. This gas, according to the World Health Organization, is the leading cause of lung cancer in non-smokers. Radon is considered the sixth most common cause of all cancers.

The most common objects where radon accumulates in high concentrations:

Radon measurements in residential, production premises for compliance sanitary standards- This is a way to save people's lives and health. If during the research it turns out that workers are production sites been exposed to radon for a long time, this will entail serious financial costs. Therefore, radon measurements should be ordered not only for social, but also for economic reasons.

Measuring background radiation in various environments

Radon measurements are carried out:

• in tap water, in water from wells and wells. The gas dissolves well in water, is not noticeable by smell or taste, and its presence can only be detected with special devices. Radiological analysis of water also involves studying its composition for the presence of alpha- and beta-emitting radionuclides, determining the specific activity of uranium, lead, radium, polonium;
• in the air;
• in the soil.

In the process of measuring background radiation in laboratory conditions, the following is determined:

• equivalent equilibrium volume activity (ERV) of radionuclides;
• radon flux density.

Issues of radiological safety are currently quite acute, and therefore radiological research is mandatory when monitoring the ecological state of agricultural lands, territories of settlements and industrial zones, when conducting engineering surveys for construction in order to identify sources of radiation contamination and prevent negative impacts radiation on human health.

Specialists of our Center conduct radiological studies using modern radiometers and spectrometers.

During a radiation survey of the territory, the following radiological studies are performed:

• dosimetric monitoring, during which gamma-ray survey of the area is carried out;
• background values ​​of equivalent dose rate of the territory;
• areas of radioactive contamination, their scale and composition of contamination are identified;
• sampling of radiation monitoring samples from objects and subsequent laboratory spectrometric measurement of the content (specific activity) of radionuclides in soils and soils is carried out;
• The radon flux density from the soil surface, in pits and in the air of buildings located on the construction site is measured, and the potential radon hazard of the surveyed area/building is assessed.

Based on the data obtained, conclusions are drawn about the compliance or non-compliance of the studied indicators with the requirements of regulatory documents (NRB-99/2009, OSPORB-99/2010, etc.).

What is radiological contamination?

Radioactivity is the spontaneous transformation (decay) of the atomic nuclei of some chemical elements, leading to a change in their atomic number and mass number. Such chemical elements are called radionuclides. Atoms of the same element having different mass numbers are called isotopes.

Naturally occurring radioactive substances are widely distributed in nature. Their radiation creates a natural radiation background of external irradiation. The natural radioactivity of soils is mainly due to the content of uranium, radium, thorium and the isotope potassium-40. Usually in soils they are in a highly dispersed state and distributed relatively evenly.
Activity is a measure of the amount of radioactive substance expressed by the number of radioactive transformations per unit of time. The unit of activity is one nuclear transformation per second. In the SI system this unit is called the becquerel (Bq). Until recently, a special (non-systemic) unit of activity was widely used - the curie (Ci): 1 Cu = 3.7 1010 nuclear transformations per second. The relationship between the indicated units of activity: 1 Bq ~ 2.7 1011 Cu. During radiological monitoring of natural objects, specific activity is determined, which characterizes the activity of a radionuclide per unit mass or volume of the sample.

The development of life on Earth has always occurred in the presence of a natural radioactive background. Its sources are cosmic radiation and natural radionuclides (RNN). soils As a result of human activity, artificial radionuclides appeared in the biosphere, and the amount of natural radionuclides extracted from the bowels of the Earth with oil, coal, gas, and ores increased. The problem of global contamination of soils and soils with radioactive isotopes of some elements arose with the development of the nuclear industry and testing of nuclear and thermonuclear weapons.

Particularly significant radioactive contamination of soils, soils and the biosphere as a whole occurs during emergency situations.

Radioactive contamination of soils in landscapes and ecosystems is currently caused mainly by two radionuclides: cesium-137 and strontium-90. Therefore, the gross content of research objects is determined, first of all, by them. In soils of long-term intensive agroecosystems, in addition, the gross amount of potassium-40 is determined.

Cesium-137 is a beta and gamma emitter with a maximum beta energy of 1.76 MeV and T1/2 = 30.17 years. The high mobility of cesium-137 is determined by the fact that it is a radioisotope of an alkaline element.

Strontium-90 has a half-life of 28.1 years and is a beta emitter with a maximum energy of 0.544 MeV. It is considered one of the most biologically mobile. The fixation and distribution of this radionuclide in the soil is mainly determined by the patterns of behavior of the isotopic carrier - stable strontium, as well as the chemical analogue - stable calcium.

Potassium-40 is a beta emitter with an energy of 1.32 MeV and T1/2 = 1.28 109 years. Each gram of natural potassium contains 27 Bq of potassium-40. In progress economic activity human flows of this radionuclide in the components of the biosphere increase - an additional 6.2 1016 Bq of potassium-40 is involved in the natural cycle. With an average application rate of potassium fertilizers of 60 kg/ha, potassium-40 1.35 106 Bq/kg enters the soil (Aleksakhin et al., 1992).
The most dangerous pollutants of agroecosystems - long-lived radionuclides - cesium-137 and strontium-90 require special attention. Their share in the mixture of fission products increases over time. Being included in the biological chain “soil - plant - animal - human”, they have a damaging effect on human health. The “Cesium period” will last about 300 years.

The main criterion characterizing the degree of radioecological safety of a person living in a contaminated area is the average annual effective dose. The unit of effective dose is the sievert (Sv). To assess the general consequences of exposure of the population in the case of living in a contaminated area, the collective effective dose is used, which is the product of the average effective dose for a group of people by the number of individuals in this group. The International Commission on Radiological Medicine has recommended a dose equal to 1 mSv/year (0.1 rem/year) as a limit for the radiation dose to the population.

The main routes of human exposure that must be taken into account when estimating actual effective doses include: external exposure from gamma-emitting radionuclides in a radioactive cloud, external exposure from aerosol and particulate fallout, internal exposure through food chains and through inhalation. Our laboratory carries out radiological analysis of soil according to modern standards, we accept applications by phone and from the website.

Radiation safety criteria

How are radiological examinations carried out?

Determination of NRN in the soil of areas allocated for construction is carried out by gamma spectrometric analysis of samples. Soil and soil samples are taken using special samplers, as well as when drilling geotechnical wells.

Sampling and processing of samples and determination of the isotopic composition of radionuclide concentrations must be carried out in laboratories accredited for this type of work.

Route gamma survey of the territory should be carried out with the simultaneous use of search dosimeters-radiometers and dosimeters. Dosimeters-radiometers are used in the “Search” mode to detect areas (points) of radiation anomalies. Dosimeters are used to measure DER at control points (grid with a step of no more than 10x15 m). Measurements are carried out at a height of 0.1 m above the soil surface, as well as in geotechnical wells - gamma ray logging.

The equivalent dose rate (EDR) of external gamma radiation should not exceed 0.3 μSv/hour. Areas where the actual EDR level exceeds that determined by the natural gamma background are considered anomalous. In areas of identified gamma background anomalies, the intervals between control points should be consistently reduced to the size necessary to delineate zones with an DER level > 0.3 µSv/hour.

In such areas, in order to assess the value of the annual effective dose, the specific activities of man-made radionuclides in the soil must be determined and, in agreement with the state sanitary and epidemiological surveillance authorities, the issue of the need for additional research or decontamination measures must be resolved.

If a radiation anomaly with DER > 0.3 μSv/h or higher is detected, special services must be informed.

The radon hazard of an area is determined by the density of radon flux from the ground surface and its concentration in the air of nearby already constructed buildings and structures. Measurement of radon flux density is carried out at control points located at the nodes of a rectangular grid with a step determined taking into account the potential radon hazard of the area (20x10, 10x15, 50x25), but not less than 10 points per area.

Radon flux density is measured on the soil surface, the bottom of a pit, or at the bottom level of a building’s foundation. It is not allowed to carry out measurements on the surface of ice and on areas flooded with water.

Radon flux density is measured by exposing storage chambers with radon sorbent at control points, followed by determining the flux value using radiometric installations based on the activity of beta or gamma radiation from daughter products of radon absorbed by the sorbent.
Based on the data obtained, the class of required radon protection of the building is calculated.
The results of radiation-ecological surveys are presented in the form of a technical report.

The report includes the following materials and data:

• site plan indicating the DER at control points;
• results of work on gamma survey, determination of NRN in the soil, assessment of the radon hazard of the site;
• conclusion on the radiation safety of this site, and, if necessary, recommendations for improving the safety level.
