Biological Effects of Radiation02:59

Biological Effects of Radiation

17.7K
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...

Radiation: Applications

1.7K
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...

Generating Electromagnetic Radiations

6.9K
The German physicist Heinrich Hertz (1857–1894) was the first to generate and detect certain types of electromagnetic waves in the laboratory. Starting in 1887, he performed a series of experiments that confirmed the existence of electromagnetic waves and verified that they travel at the speed of light. Hertz used an alternating-current RLC (resistor-inductor-capacitor) circuit that resonated at a known frequency and connected it to a loop of wire. High voltages induced across the gap in...

Radiation Pressure: Problem Solving01:09

Radiation Pressure: Problem Solving

815
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...

Momentum And Radiation Pressure01:20

Momentum And Radiation Pressure

2.4K
An object absorbing an electromagnetic wave would experience a force in the direction of propagation of the wave. This force occurs because electromagnetic waves contain and transport momentum. The force accounts for the wave's radiation pressure exerted on the object. Maxwell's prediction was confirmed in 1903 by Nichols and Hull by precisely measuring radiation pressures with a torsion balance. The measuring instrument had mirrors suspended from a fiber kept inside a glass container.

Summary
This summary is machine-generated.

Weekend radiotherapy (RT) for oncology emergencies is often necessary. A review found that most urgent RT treatments administered on weekends were justified by documented indications and published literature.

Area of Science:

  • Oncology
  • Radiation Oncology
  • Emergency Medicine

Background:

  • Prompt assessment and treatment of oncology emergencies are crucial for symptom management, function preservation, and quality of life.
  • Weekend radiotherapy (RT) is sometimes required for patients with urgent oncological needs.
  • This study aimed to evaluate the justification for weekend RT at an institution.

Purpose of the Study:

  • To review the delivery of urgent radiotherapy (RT) on weekends.
  • To determine the proportion of weekend RT courses with documented indications justifiable by published literature.
  • To assess the clinical necessity of after-hours RT in oncology emergencies.

Main Methods:

  • Retrospective review of patients receiving RT on weekends (January-July 2009).
  • Data collected included demographics, disease site, functional status, and reason for after-hours treatment.
  • Literature search conducted to compare with clinical practice guidelines and published evidence.

Main Results:

  • 108 patients received 132 courses of weekend RT, predominantly for palliative intent (97.0%) and spine RT (46.2%).
  • An average of 18.9 weekend treatment courses were administered monthly.
  • 72.1% of after-hours treatments had documented reasons justifiable by published literature.

Conclusions:

  • Weekend RT delivery necessitates specific clinical justification due to resource and technical considerations.
  • The decision for after-hours RT is currently at the discretion of the treating radiation oncologist.
  • The majority of indications for weekend emergency RT in this cohort were supported by published evidence.
