Radiation: Applications

1.6K
The average temperature of Earth is the subject of much current discussion. Earth is in radiative contact with both the Sun and dark space; it receives almost all its energy from the radiation of the Sun and reflects some of it into outer space. Dark space is very cold, about 3 K, so Earth radiates energy into it. For instance, heat transfer occurs from soil and grasses, the rate of which can be so rapid that frost can occur on clear summer evenings, even in warm latitudes.
The average...

Radiation Pressure: Problem Solving

665
The radiation pressure applied by an electromagnetic wave on a perfectly absorbing surface equals the energy density of the wave. The wave's momentum also gets transferred to the surface when an electromagnetic wave is entirely absorbed by it. The rate at which momentum is transmitted to an absorbing surface perpendicular to the propagation direction equals the force on the surface.
The average value of the rate of momentum transfer divided by the absorbing area represents the average force...

Biological Effects of Radiation02:59

Biological Effects of Radiation

17.2K
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...

Dual Nature of Electromagnetic (EM) Radiation01:10

Dual Nature of Electromagnetic (EM) Radiation

3.4K
Electromagnetic (EM) radiation consists of electric and magnetic field components oscillating in planes perpendicular to each other and mutually perpendicular to radiation propagation through space. EM radiation can be classified as a wave, characterized by the properties of waves such as wavelength (denoted as λ) and frequency (represented by ν).
Wavelength is the distance between two consecutive peaks (the highest point) or troughs (the lowest point) in the wave. Frequency is the number of...

Mutations01:35

Mutations

42.3K
Mutations are changes in the sequence of DNA. These changes can occur spontaneously or they can be induced by exposure to environmental factors. Mutations can be characterized in a number of different ways: whether and how they alter the amino acid sequence of the protein, whether they occur over a small or large area of DNA, and whether they occur in somatic cells or germline cells.
Chromosomal Alterations Are Large-Scale Mutations
While point mutations are changes in a single nucleotide in...

Summary

Two-dimensional (2D) materials show remarkable radiation hardness for space electronics. However, their tolerance to space radiation is significantly influenced by their surrounding environment, such as the substrate.

Area of Science:

  • Materials Science
  • Condensed Matter Physics
  • Nanotechnology

Background:

  • Two-dimensional (2D) materials possess unique properties suitable for space applications due to low weight, small size, and low power consumption.
  • Electronic devices in outer space require high radiation hardness to withstand energetic particles.
  • Recent studies suggest 2D materials exhibit extraordinary radiation tolerance, contrary to initial expectations.

Purpose of the Study:

  • To provide an overview of recent studies on the radiation hardness of 2D materials.
  • To discuss the origin of the high radiation tolerance in 2D materials.
  • To analyze the influence of the environment on the radiation tolerance of 2D material-based devices.

Main Methods:

  • Review of experimental and theoretical data on 2D materials under irradiation.
  • Analysis of the response of reduced-dimensionality systems to energetic particle beams.
  • Investigation of the role of substrates and environmental factors on radiation tolerance.

Main Results:

  • Free-standing 2D materials demonstrate significant resilience to space radiation conditions.
  • The substrate and surrounding environment critically affect the radiation tolerance of 2D materials.
  • The inherent properties of 2D materials contribute to their radiation hardness, but environmental factors can alter this.

Conclusions:

  • While 2D materials are inherently radiation resilient, their practical application in space requires careful consideration of the substrate.
  • Environmental factors, particularly the substrate, play a crucial role in determining the overall radiation tolerance of 2D material-based electronic devices.
  • Further research is needed to optimize 2D material systems for robust performance in harsh space environments.
