Hand-foot monitors

For the supeiwision of the persons working in radiochemical laboratories, pocket dosimeters (generally ionization dosimeters) and film dosimeters are used. The lower detection limits of these dosimeters vary between about 1 and 40 mR. Furthermore, hand foot monitors are installed near the exit of the laboratories, by which external contamination can be detected. In the case of suspected internal contamination, the person is checked by means of a whole-body counter which allows detection of y-ray emitters with high sensitivity. The presence of natural contributes essentially to...

The nonportable instruments are set at fixed locations to detect the radiation field they are usually equipped with an alarm that will provide an audio and/or visual signal when the field intensity exceeds a preset limit. Examples are continuous air monitors and personnel monitors (e.g., hand, foot, and whole body). A list of several health physics instruments and their characteristics is given in Table 16.11.

There are several types of portable instruments used in the HCF. These instruments are used routinely by RCTs to monitor and survey the facility, monitor the movement of materials, and monitor facility personnel. Hand and foot monitors and whole body counters are used to routinely monitor all personnel exiting the facility. 

In all laboratory experiments and procedures, it is important that hazards be controlled or managed primarily by engineering measnres, snch as a laboratory hood, local exhaust ventilation, or a glove box. Ventilated enclosures can often be used for weighing chemicals. Best practices also include having a laboratory under negative pressure with respect to the adjacent hallway so that hazardous chemical vapors are kept in the laboratory. In same cases, such as with the use of radioactive materials, personal hand, foot, or full-body monitors may be needed to control the spread of material into areas outside controlled laboratory facilities. 

A survey counter is a gas filled detector used to detect spilled radioactive materials that can be hazardous for the operators or may disturb accurate dose measurements. Survey counters can be mounted at critical places to measure the radiation level in rooms continuously. A hand-foot-clothing monitor is a suitable and obligatory instrument to detect possible contamination before leaving the area where radioactive materials are handled. 

A. 1207. This section shall describe the radiation and contamination monitoring stations, including fixed hand and foot monitors, portal monitors (if used) and portable activity monitors located at these stations. The portable and laboratory equipment and instrumentation for performing radiation and contamination surveys, for contamination control between different access zones, for airborne radioactivity monitoring/sampling and for personnel monitoring shall also be described. 

The radiation monitoring system was designed to allow continuous monitoration of radiation levels inside the critical facility. It is composed by 27 radiation monitoring channels, being 14 area monitors, 8 process monitors, 3 air monitors, 1 hand and foot monitor and 1 monitor of the "portal" type. 

This monitor is designed to monitor radioactive material deposited on clothes, shoes, and body surfaces of a worker in an isotope laboratory. Therefore, the device contains foot and hand detectors. It is usually posted at the exit of the laboratory. The purpose of the monitor is to avoid the spread of radioactive substances and to discover any internal contamination. 

The push-button switch on the remote reflectance probe was rewired into a foot-switch so that the analyst, whose gloved hands were inside the glovebox manipulating each sample, could initiate a scan most efficiently. Each scan was displayed in real time on the computer s monitor in log(l// ) mode (absorbance vs. wavelength). Some samples were scanned more than once, and absorbances were saved at 2 nm increments (700 data points) in the computer and on a floppy disk. About 20 plastic or rubber samples were analyzed each day. If this number seems low, know that for each sample other people were making written records, audio recordings, and multicamera videotape records for complete documentation of the procedure.
