The relative attraction of a nucleus for electrons. Using the periodic table, the most electronegative atom is fluorine (upper right), with decreasing electronegativity as one traverses the table down or to the left.  

In electron microscopy, having a density that prevents penetration by electrons.  

Electron microscopic imaging of rapidly frozen molecules and crystals in solution.  

An adjunct to external beam radiation therapy in which small focused fields of radiation are applied to a tumor in an attempt to destroy it. Electron boost radiation is used to treat some breast cancers.  

A technician who assists the neurologist in recording and analyzing bioelectric potentials that originate in muscle tissue. This includes the operation of various electronic devices, maintenance of electronic equipment, assisting with patient care during testing, and record keeping.  

To the passage of electricity in a current or motion produced by it.  

Massage combined with electrical treatment.  

Magnetism produced by an electric current. The field of physics that explores the interplay between electricity and magnetism.  

The complete range of wavelengths of electromagnetic radiation. Name given to all of the forms of energy (or radiation) that exist. The complete spectrum of wavelengths or frequencies of electromagnetic radiation, spanning from the shortest cosmic rays to the longest radio waves.  

All forms of energy emanating from an electrical source. Included are the fields produced by light, radio, x-rays, and gamma rays. The higher the frequency of the fields produced, the more energy is contained. Thus, the radiated energy from the 60-cycle frequency of an ordinary household electric line is quite small. The long-range effects of…
