Nuclear Overhauser Enhancement (NOE)01:07

Nuclear Overhauser Enhancement (NOE)

857
Irradiation of a spin-active nucleus causes an increase or decrease in the signal intensity of neighboring nuclei that are not necessarily chemically bonded or involved in J-coupling.  This phenomenon, called the Nuclear Overhauser Enhancement (NOE), results from through-space interactions between the nuclear spins. The NOE effect decreases with increasing internuclear distance and is generally not observed beyond 4 angstroms. In NOE, dipole-dipole interactions between neighboring...

Biological Effects of Radiation

16.1K
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...

Scanning Electron Microscopy01:07

Scanning Electron Microscopy

4.5K
A scanning electron microscope (SEM) is used to study the surface features of a sample by using an electron beam that scans the sample surface in a two-dimensional manner. Typically, areas between ~1 centimeter to 5 micrometers in width can be imaged. SEM can be used to image bacteria, viruses, tissues as well as larger samples like insects. Conventional SEM gives a magnification ranging from 20X to 30,000X and spatial resolution of 50 to 100 nanometers.

Summary
This summary is machine-generated.

Neutron survey meters can drift due to the radiation soaking effect, where prolonged high-intensity radiation causes dose rate readings to increase. This study identifies the cause and discusses mitigation techniques for 3He and BF3 proportional counters.

Area of Science:

  • Nuclear instrumentation and radiation detection.
  • Metrology and calibration of radiation measurement devices.

Background:

  • Neutron survey meters using 3He and BF3 proportional counters exhibit response drift.
  • This drift, known as the radiation soaking effect, is characterized by increasing dose rate readings under high-intensity radiation.
  • The effect is attributed to charge accumulation on internal insulating surfaces.

Purpose of the Study:

  • To investigate the radiation soaking effect in neutron survey meters.
  • To identify the cause of response variance between different instruments.
  • To explore potential mitigation techniques for the radiation soaking effect.

Main Methods:

  • Assessing the magnitude of the radiation soaking effect in various instruments under identical high-intensity radiation conditions.
  • Analyzing the physical mechanisms responsible for charge accumulation within the detectors.
  • Evaluating existing calibration compensation measures.

Main Results:

  • A specific reason for the observed variance in detector response has been identified.
  • The study quantifies the magnitude of the radiation soaking effect across different neutron survey meters.
  • Understanding of charge accumulation mechanisms has been enhanced.

Conclusions:

  • The radiation soaking effect in neutron survey meters is a significant factor affecting accuracy.
  • The identified cause of response variance provides a basis for instrument selection and understanding.
  • Potential methods for mitigating the effect and restoring baseline sensitivity are discussed.
