Wiping tests

A thorough inspeetion of equipment, whieh may inelude frisking or a wipe test, helps determine the duration of and methodology seleeted for deeontamination. All equipment parts should be eonsidered highly eontaminated, removed, and replaeed before the equipment leaves the worksite. Porous items (i.e., wooden truek beds, eloth hoses, wooden handles) usually eannot be thoroughly eleaned and should be disearded (as hazardous waste if neeessary). 

Simple Solvent Wipe Test. The simplest test method to determine the extent of cure is to rub a cotton swab that has been soaked in a suitable solvent (e.g., methyl ethyl ketone) against the surface of the cured adhesive. If the adhesive softens, it is very far from a fully cured condition, and the degree of softness is a very gross indication of the degree of cure. 

However, because it contains 5 millicuries of 63Nickel, the ECD is covered by a General License requiring a periodic wipe test and the filing of a form with the respective state s Department of Health or with another adequate authority. Its advantages are (Venn 2000) ...

All necessary accessories for PET studies, including a dose calibrator, 18F-FDG storage, a wipe test counter, a survey meter, and so on, are kept in the van. The mobile PET van moves daily to different clients sites according to the schedule made prior to the day of examination. The patient s PET study is performed and the data are processed in the van, while the interpretation can be made either at the van or at the home site of the mobile PET company.

The test method used was a solvent wipe test where specified pressures and solvent concentrations are applied to each coated sample. Data generated was number of seconds to pinhole distortion which relates to amount of cure. Figure 4 elucidates the results. 

E. Broken tritium devices indoors may result in tritium contamination of the workbench, table, or the surrounding area. The area must be cordoned off and restricted until a wipe test in the area indicates that no contamination remains on the surface. 

F. Due to tritium s low energy level, portable detection equipment may not be available that will detect its presence. The only method of detecting tritium is by performing wipe tests and evaluating the wipe test on a liquid scintillation counter. 

E. Because of the weak beta radiation, tritium is NOT readily measured by the Geiger-Mueller counter used with most fielded radiac instruments and requires wipe testing swipes and a liquid scintillation detector to determine the level of contamination.

NOTE The P-particle source is 12 mCi of Ni electroplated on an electrode. Even though P-particles penetrate only 8-10 cm of air and the detector cover completely shields the source, in the U.S. this is considered to be a radioactive source and cannot be discarded when the instrument wears out. It must be labeled as being radioactive, it must be tested twice a year by wipe tests, and it must be sent to a licensed operator if it needs cleaning. It must be disposed of separately as a radioactive source and a record kept for its entire lifetime. This is not considered trivial by the U.S. Nuclear Regulatory Commission (NRC), even though common sense indicates otherwise. 

Finally, the liquid droplet will impact the surface to be coated and splash as depicted in Figures 5.20 and 5.21 and also shown in the results of a wipe test (Figure 6.7). Figure 5.20 shows the surface of an APS hydroxyapatite coating with...

Different surfaces (floor, roof, walls) were selected to perform the assays. On those surfaces the reagent, liquid at room temperature (95% of Nixolen and 5% of sodium alkoxide), was spread at room temperature to produce a liquid film such a film at the same time avoided the transfer of the contaminant to the environment. After about 90 hours of action at room temperature, the liquid film was then removed. Samples were taken either on the surfaces (wipe tests, before and after the treatment were made) and on the removed reagent. 

The usual hand measuring instruments react even to traces of iodine with frightening crackling. Hence, working with iodine rarely leads to the extensive contamination of tools and workplace as can often be observed with After all, can only be detected with time-consuming wipe tests, and in my experience researchers do this at most once a year. 

Wipe-test the autoclave interior for surface contamination regularly. 

The bulk and trace detection methods have different characteristics, and they complement each other s weak points. Therefore, the combined use of bulk detection and trace detection is effective to improve security at important facilities. Bulk detection is a popular meliiod that has been widely used, but trace detection technologies have become increasingly necessary as security concerns have grown. For example, wiping tests for luggage using ion mobility spectroscopy or chemiluminescence detection have been implemented as part of aviation security. 

LA is a major component of impurities. In practical wiping tests of explosives, a suitable amount of LA is collected by wiping luggage, and it is not necessary to add extra LA. During security applications in the field, the heating unit and the ion source of the explosives...
