Transmission-based Precautions II: Airborne and Protective Environment01:25

Transmission-based Precautions II: Airborne and Protective Environment

Transmission-based precautions are for patients infected or suspected to be infected (or colonized) with organisms posing a significant risk to others. The transmission precautions include airborne and protective environment precautions.
Airborne precautions:
Use airborne precautions when treating patients known or suspected to have diseases that spread through the air—for example, tuberculosis or measles. These organisms are present in smaller droplets expelled by an infected person and...
Biological Effects of Radiation02:59

Biological Effects of Radiation

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 produce ions...
Radiation: Applications01:17

Radiation: Applications

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 Solving01:09

Radiation Pressure: Problem Solving

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 per...

Absorption of Radiation

The rate of heat transfer by emitted radiation is described by the Stefan-Boltzmann law of radiation:

Area of Science:

  • Radiation physics
  • Atmospheric science
  • Aviation safety

Background:

  • Cosmic radiation poses a significant health risk to aircrew.
  • Accurate dose assessment is crucial for radiation protection in aviation.

Purpose of the Study:

  • To develop a model for interpolating radiation dose rates.
  • To create a tool for estimating aircrew radiation exposure on global flight routes.

Main Methods:

  • Utilized empirical data from a tissue equivalent proportional counter.
  • Derived a dose-rate interpolation model.
  • Integrated the dose-rate function over flight paths to develop the PCAire code.

Main Results:

  • A model capable of interpolating dose rates for any global position, altitude, and date was established.
  • The Predictive Code for Aircrew Radiation Exposure (PCAire) was developed.
  • PCAire provides estimates of total dose equivalent for any route and solar cycle period.

Conclusions:

  • The developed model and PCAire code enable accurate prediction of aircrew radiation doses.
  • This tool supports radiation safety protocols for aviation.
  • Global radiation exposure can now be estimated more effectively for flight planning.
