| Plastic Scintillators offer high performance, ease of handling , mechanical stability at a relatively Low Cost when compared to | ||
| Inorganic Scintillators such as NaI(TI). The versatility of plastic scintillators makes them the ideal choice for large area and | ||
| specially shaped detectors. In particular, The composition formula for RP-200 dates back to the early 1970s and has been | ||
| modified to provide the lowest Cost Plastic Scintillator available where timing is a secondary issue concomitant with as good | ||
| an Efficiency as the RP-408 and RP-400. | ||
| RP-200 combines two important properties: | ||
| Lowest Cost Scintillator Type with the SAME COUNTING EFFICIENCY. | ||
| Long Optical Attenuation Length - Typical measurements of 4 meter optical attenuation length are achieved in strips of | ||
| cast sheet in which a representative size is 2 cm x 20 cm x 300 cm. | ||
| The emission spectrum ( 435 nm) is well matched to common photomultipliers. RP-200 is the detector of choice for many | ||
| industrialapplications such as in gauging and environmental protection where high sensitivity of signal uniformity are critical | ||
| operating requirements. Commercially, it is the most preferred Economy Plastic Scintillator in use. | ||

| Effects of liquids | ||
| The plastic scintillators are soluble in aromatic solvents, acetone chlorinated solvents etc. They are unaffected by water, | ||
| dilute acids, alkalis, lower alcohols, pure methyl alcohol, silicone grease or fluid. | ||
| Standard Sizes and Shapes | ||
| Sheet Sizes range up to 200" (5m) long by 36" (914mm) wide. Blocks are available up to 96" (2.5m) long, Rods up to 48" | ||
| (1220mm) diameter are manufactured. Call for standard sizes of annuli, well counters, thin films and spheres. | ||
| Handlingandcleaning | ||
| Plastic scintillators sheets are supplied with a protective paper that should not be removed until ready for use. it is advisable | ||
| to handle all plastic scintillators with cotton to terylene gloves. If the scintillator requires cleaning we recommend a dilute solution | ||
| of liquiddetergent and a selvyt polishing cloth or BPC grade cotton wool. alternatively, Rexon can supply an excellent | ||
| cleaning/polishing cream. Use of this can often increase the measured light attenuation length. Ethanol or methanol may be used. | ||
| Machining instructions are available upon request. | ||
