The damage conditions of each rubber give clear information on the various rubbers exposed to ionizing radiation in the nuclear industry. The components in the nuclear equipment are gas flue outlets, recycle and process pipings, process tanks, and rake arms and agitators. [Pg.125]

With older vessels requiring repairs, one has to make a judgment as to how to repair the vessel. Basically, there are two options for repair. One is to use a chemically curable lining that is appropriate to match the lining in the vessel. Chemical cure linings may have high leech-able sulfite levels, even when cured with steam. Therefore, chemical cure linings are only considered acceptable on minor repairs. [Pg.125]

Fifteen -blockers have also been activated photochemically with the same radiation unit (Heraeus, Hanau Osram STE 501 UV lamp TNN 15-3200/721)[23]. Their detection limits, the working range and associated standard deviation of the method are listed in Table 1 below. The blue fluorescence of the chromatogram zones (Xg 5 = 313 nm, > 390 nm) was measured after dipping the chromatogram in liquid paraffin - n-hexane (1 + 2). Figure 18 illustrates the separation of seven P-blockers. [Pg.18]

Since 1925, The International Commission on Radiation Units and Measurements at Bethesda, Maryland has been publishing reports updating the definitions and units for measurements of various radiation-related quantities. Of these ICRU Reports, special mention may be made of reports no. 19 (1971) [radiation quantities and units], 33 (1980) [radiation quantities and units], 36 (1983) [microdosimetry], 47 (1992) [thermoluminiscent dosimetry], and 51 (1993) [radiation protection dosimetry]. A succinct description of various devices used in dosimetry, such as ionization chambers, chemical and solid-state dosimeters, and personnel (pocket) dosimeters, will be found in Spinks and Woods (1990). In this section, we will only consider some chemical dosimeters in a little detail. For a survey of the field the reader is referred to Kase et at, (1985, 1987), McLaughlin (1982), and to the International Atomic Energy Agency (1977). Of the earlier publications, many useful information can still be gleaned from Hine and Brownell (1956), Holm and Berry (1970), and Shapiro (1972). [Pg.363]

Cooperate with the International Commission on Radiological Protection, the International Commission on Radiation Units and Measurements, and other national and international organizations, governmental and private, concerned with radiation quantities, units, and measurements and with radiation protection. [Pg.101]

In 1993, ANSI issued a revised version of this standard (ANSI, 1993). The 30 cm diameter sphere of soft tissue of density 1 g cm was modified to a 30 cm X 30 cm X 16 cm slab of soft tissue with the composition defined by the International Commission on Radiation Units and Measurements [ICRU (1992)]. NVLAP and NRC have announced plans to use the revised version (NVLAP, 1994). [Pg.8]
