Will Radiation Control Be by Reason Or Regulation?
Health Physics, 1988Following a very brief review of the development of our present radiation-protection philosophy, attention is directed to what the author sees as current problems. The only prognostication will be that at least certain of the problems outstanding or developing today will be among those that will have to be addressed in the coming four decades.

A Radiation Control and Monitoring System
The Journal of the American Dental Association, 1972A device that can be installed in existing dental X-ray units controls and monitors radiation exposure to the patient. The radiation control unit emits a preset value of radiation and terminates the exposure. The attached printing device prints information set on the machine, such as milliroentgen values and kilovoltages, the tooth number, and date.

Radiation control of refractories
Refractories, 1990X-ray and electron-x-ray methods of control are useful for detecting the main types of defects in refractories for MNLZ (continuous casting). The sensitivity of the control corresponds to the requirements of refractories. X-ray control of refractories may be carried out on the x-ray-television introscope RI-60TK and the electron-x-ray equipment ERGA-03.

Controlling the Radiation of Heat
2005Abstract One essential role of a building in providing thermal comfort is controlling the flow of thermal radiation to and from the human body. Sometimes a building must protect the body from an excessive influx of radiant heat from the sun or from sun-warmed objects. At other times, protection is needed to prevent an excessive radiation

A system for controlling a radiator valve by using a sensor to obtain a current temperature measurement, and then operating a motor to change a valve position based on the temperature measured. If the temperature is within a first range of a target temperature, the valve is maintained in the current position and if the temperature is outside the first ...
