AH x-ray equipment must be periodically inspected and the output monitored and caUbrated to minimize the chance of accidental overexposure. Another concern involves radiation accumulation by medical personnel operating x-ray equipment. Although the dose to any one patient may be low, the accumulated dose to a clinician performing multiple exams each day over the course of a year is great. Therefore, personnel working with x-ray equipment must take precautions constandy to minimize and monitor exposure. Lead aprons and film badges are used to minimize exposure and to monitor accumulated dose, respectively. 

Health and Safety. Remover formulas that are nonflammable may be used in any area that provides adequate ventilation. Most manufacturers recommend a use environment of 50—100 parts per million (ppm) time weighted average (TWA). The environment can be monitored with passive detection badges or by active air sampling and charcoal absorption tube analysis. The vapor of methylene chloride produces hydrogen chloride and phosgene gas when burned. Methylene chloride-type removers should not be used in the presence of an open flame or other heat sources such as kerosene heaters (8).

Beeause the diisoeyanate is used in exeess, there is usually free monomer present. Isoeyanates are hazardous materials particularly upon inhalation and skin contact. Chronic exposure ean lead to sensitization. The adhesives must therefore be used with proper ventilation and should not come in eontact with the skin in the unreaeted state. Vapor monitoring badges for employees and periodie real time vapor monitoring around process equipment is reeommended. 

Passive diffusion sorbent badges are useful for screening and monitoring certain chemical exposures, especially vapors and gases. 

Badges are available to detect mercury, nitrogen oxides, ethylene oxide, formaldehyde, etc.

Payment for gas consumed is made based on the consumption as registered on a meter. Meters used for billing purposes are checked for accuracy and badged by the Department of Energy. These meters are known as primary meters. Those used by the user for monitoring the consumption of plant, etc. are known as check meters (often erroneously referred to as secondary meters).

Recent Uses of Solid-Surface Luminescence Analysis in Environmental Analysis. Vo-Dinh and coworkers have shown very effectively how solid-surface luminescence techniques can be used for environmentally important samples (17-22). RTF has been used for the screening of ambient air particulate samples (17,18). In addition, RTF has been employed in conjunction with a ranking index to characterize polynuclear aromatic pollutants in environmental samples (19). A unique application of RTF reported recently is a personal dosimeter badge based on molecular diffusion and direct detection by RTF of polynuclear aromatic pollutants (20). The dosimeter is a pen-size device that does not require sample extraction prior to analysis. 

Advantages and disadvantages of thermal desorption are listed in Table 9.3. (Charcoal badges are also available which require no pump these are termed passive samplers .) Instruments are also available to give direct readout of atmospheric levels of pollutant.

In the light of the inns cressets, I saw my father standing, unarmed and in his nightgown, surrounded by men bearing Warwick s badge. My mother stood beside him, dressed all by guess, a bundle on the cobbles beside her, and behind them loomed the bulk of one of the ships. 

A drop of wine runs from the corner of my mouth and falls onto the pillow. I wipe it away. And today I learned how right I was to fear for Edward. Did they tell you that Richard has thrust him aside Stephen is silent. It must be for his allegiance s sake he is Richard s man, after all, wears his boar badge as well as his own master s, as so many do. Or maybe he does not understand. I would have wished they had kept it from me, except that there are still a few hours left to pray for Edward. Not for his rule, now. For his life. ...
