Summary
Alpha scintillation cells offer efficient radon detection in soil gas. This study calibrates the 110 A active radon cell, determining its sensitivity and efficiency for accurate measurements.
Area of Science:
- Environmental Science
- Nuclear Physics
- Geophysics
Background:

Purpose of the Study:
- To calibrate the 110 A active radon cell for soil gas analysis.
- To determine the sensitivity and registration efficiency of the active scintillation cell.
- To investigate radon gas accumulation and emanation rates.
Main Methods:
- Utilized a 110 A active radon cell for measurements.
- Adapted a nuclear system to monitor radon gas accumulation.
- Investigated radon growth curves and emanation, leakage, and back diffusion rates.
Main Results:
- The sensitivity of the 110 A active cell was determined to be 0.015895 cpm/Bq/m³.
- The registration efficiency of the cell was found to be 59%.
- Achieved compatibility between practical measurements and theoretical predictions for radon activity.
Conclusions:
- The 110 A active radon cell is a reliable tool for soil gas radon detection.

The most common types of radioactivity are α decay, β decay, γ decay, neutron emission, and electron capture.
Alpha (α) decay is the emission of an α particle from the nucleus. For example, polonium-210 undergoes α decay:

All radioactive nuclides emit high-energy particles or electromagnetic waves. When this radiation encounters living cells, it can cause heating, break chemical bonds, or ionize molecules. The most serious biological damage results when these radioactive emissions fragment or ionize molecules. For example, α and β particles emitted from nuclear decay reactions possess much higher energies than ordinary chemical bond energies. When these particles strike and penetrate matter, they...

Radioactivity is a spontaneous disintegration of an unstable nuclide and is a random process, as all the nuclei in the sample do not decay simultaneously. The number of disintegrations per unit time is called the activity (A), which is directly proportional to the number of nuclei in the sample. The decay constant (λ) is an average probability of decay per nucleus in unit time.

Nuclear chemistry is the study of reactions that involve changes in nuclear structure. The nucleus of an atom is composed of protons and, except for hydrogen, neutrons. The number of protons in the nucleus is called the atomic number (Z) of the element, and the sum of the number of protons and the number of neutrons is the mass number (A). Atoms with the same atomic number but different mass numbers are isotopes of the same element.
