Biological Effects of Radiation02:59

Biological Effects of Radiation

15.1K
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...

X-ray Imaging01:24

X-ray Imaging

5.3K
German physicist Wilhelm Röntgen (1845–1923) was experimenting with electrical current when he discovered that a mysterious and invisible "ray" would pass through his flesh but leave an outline of his bones on a screen coated with a metal compound. In 1895, Röntgen made the first durable record of the internal parts of a living human: an "X-ray" image (as it came to be called) of his wife’s hand. Scientists worldwide quickly began their own experiments with...

Mutations01:35

Mutations

33.0K
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...

The Electromagnetic Spectrum02:37

The Electromagnetic Spectrum

52.5K
The electromagnetic spectrum consists of all the types of electromagnetic radiation arranged according to their frequency and wavelength. Each of the various colors of visible light has specific frequencies and wavelengths associated with them, and you can see that visible light makes up only a small portion of the electromagnetic spectrum. Because the technologies developed to work in various parts of the electromagnetic spectrum are different, for reasons of convenience and historical...

Types of Radioactivity03:23

Types of Radioactivity

16.4K
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:

  • To investigate human perception of ionizing radiation.
  • To explore the underlying mechanisms of radiation perception and radiomodulation.

Main Methods:

  • Comprehensive review of clinical and experimental literature on acute effects of ionizing radiation.
  • Analysis of sensory phenomena reported in humans exposed to ionizing radiation.
  • Examination of mechanisms including reactive oxygen species formation and ion channel activity.

Main Results:

  • Evidence suggests humans can perceive X-rays via hearing and taste sensory phenomena.
  • Identified radiomodulation as a potential mechanism, involving reactive oxygen species and TRP/K+ channels.
  • Supported claims of perception via Cherenkov radiation and ozone production.

Conclusions:

  • Humans possess the capacity to perceive ionizing radiation through various sensory modalities.
  • Radiomodulation, particularly via reactive oxygen species, is a proposed key mechanism.
  • Ionizing radiation has significant applications in medicine and research, with future potential.
