Match each chemical protective ensemble component to the correct MOPP level when it is first donned. Table 2. What method is used to estimate a radiation dose by measuring the biological response to an absorbed dose of ionizing radiation? Stations should be separated physically to prevent cross contamination and should be arranged in order of decreasing contamination, preferably in a straight line. What to do in case of a CB attack? The level and types of decontamination procedures required depend on several sitespecific factors including: Decontamination procedures must provide an organized process by which levels of contamination are reduced. You can remove radioactive materials that are on the body of others or you can remove radioactive materials if they are on your body (self-decontamination). Temperature.

It is prepared easily by diluting household bleach to one-tenth strength (ie, 9 parts water or saline to 1 part bleach). Any decontamination method that permeates, degrades, damages, or otherwise impairs the safe functioning of the PPE is incompatible with such PPE and should not be used. Scrubbing/scraping. Calculate (a) the partial pressure of each gas in atmospheres and (b) the concentration of each gas in mol/L at 0 C (Hint: Because volume is proportional to the number of moles present, mole fractions of gases can be expressed as ratios of volumes at the same temperature and pressure.). In this procedure, a dry or wet cloth, glass fiber filter paper, or swab is wiped over the surface of the potentially contaminated object and then analyzed in a laboratory. 4.
