The race for new radiation monitors
Nature Materials, 2008New dosimeters are needed to measure radiation up to extreme levels created by particle accelerators and nuclear fusion reactors. The time to develop these dosimeters is now.

Introduction to Radiation Safety and Monitoring
Journal of the American College of Radiology, 2011Ionizing radiation is used in diagnostic imaging, external-beam radiation therapy, brachytherapy, and nuclear medicine to diagnose and treat a number of common conditions. To ensure the safety of patients, providers, and surrounding staff members, it is important that the health care community become familiar with the terminology, common equipment, and

A CCD miniature radiation monitor
RADECS 2001. 2001 6th European Conference on Radiation and Its Effects on Components and Systems (Cat. No.01TH8605), 2002A miniature radiation monitor (MRM) device has been developed, which utilizes a charge-coupled device (CCD) as its sensitive element. Its shielding configuration has been designed to mitigate the displacement damage threat in space environments, while also introducing a good degree of directional sensitivity.

THE INDEPENDENT RADIATION MONITOR (I.R.M.)
American Journal of Roentgenology, 1969An independent radiation monitor (I.R.M.) is a reliable safety device for any radiation therapy room. It shows conclusively that the beam is "on." The I.R.M. is inexpensive and simple to construct.

Influence of Extraterrestrial Radiation on Radiation Portal Monitors
IEEE Transactions on Nuclear Science, 2009Cosmic radiation and solar flares can be a major source of background radiation at the Earth's surface. This paper examines the relationship between extraterrestrial radiation and the detectable background in radiation portal monitors used for homeland security applications.

Monitoring Ultraviolet Radiation
1993This chapter will focus on measurements of irradiance in the ultraviolet (UV) part of the solar spectrum. Therefore, in this chapter UV refers to solar ultraviolet radiation. To accurately measure UV is not a simple task, and many complex sources of error may produce spurious data.

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.

Transistorized Radiation Monitors
IRE Transactions on Nuclear Science, 1958The advantages of transistors over vacuum tubes in radiation instruments have long been realized but a somewhat different approach to circuit design must be followed in developing transistor instruments, as compared with that used in vacuum tube circuits, and this seems to have discouraged many from developing such circuits.

Journal of Scientific Instruments, 1949
The design and constructional details are given of a portable radiation monitor of the ionization chamber d.c. amplifier type. On the most sensitive range, a 10% meter reading denotes an intensity of 0.01 r. hr. for X- and γ-rays over the energy range 100 KeV.-3 MeV. The ionization chamber has thick air-walls (0.95 cm.
