RADeCO
SAM 940
ADM-300
450 and 451P
Potpourri
100
This is the only item that should be used to mark the outside of a used filter.
What is a pencil?
100
The SAM 940 identifies isotopes through the detection of alpha and beta particles. (True or False)
What is false? (It detects isotopes through gamma & neutron radiation through scintillation crystals).
100
The downwind team will monitor for gamma and x-ray radiation while traveling to their destination; however, they must stop along the route to take these types of radiation readings...
What is alpha and x-ray radiation?
100
For an instrument that has been off for more than 12 hrs, the recommended warm up time is...
What is 4 min? (Measurements can be taken in as little as one minute for instruments that are in equilibrium with the surrounding area.)
100
This piece of equipment was designed to measure leakage and scatter around diagnostic x-ray and radiation therapy suites. It is also ideal for site surveys.
What is the 451P and/or 450?
200
When a desired flow rate for a sample collection is 13 cfm, this switch setting is the most appropriate.
What is variable? (The toggle switch has three positions: High, Variable and Off. In the high position the air sampler will operate at it's highest possible flow rate, use this position to warm up air sampler prior to calibration. Variable allows user to adjust.)
200
Units displayed in blue in the search mode indicate....
What are the level of neutrons present? (The numbers displayed in blue show the neutron counts and those shown in black represent the gamma counts/dose rate.)
200
Technicians will operate this mode to obtain a one minute alpha reading from the RADeCo filter paper.
What is the Scaler Mode? (mode...set...set)
200
The 451P has a very low tolerance for extreme temperature and humidity. (True or False)
What is False? Temperature Range: -4 to +122 F (-20 to + 50C) Relative humidity: 0 to 100%
200
This piece of equipment requires a direct reading instrument or analytical technique to provide contaminate identification.
What is the RADeCO?
300
This is the operating range of the RADeCO.
What is 2-20 cfm? (The requested calibrated flow range by the USAF is 2- 20 CFM with an accuracy of +/- 5% of full scale (1 CFM)
300
You are sending a team out on a response. There is uncertainty as to how long it has been since the SAM 940 has been charged. Is it proper procedure to send your team in with the SAM 940 based on the green indicator on the search search mode?
What is no? (This green indicator states that you may not have enough battery. Users should recheck the Self-Test and Status Screen prior to entry)
300
Using the ADM-300 and various probes, the CERF ADVON team will be responsible to obtain background readings for what three types of radiation...
What is alpha, gamma, and x-ray radiation? Normal Background Alpha: 0 CPM Gamma: 25 uR/hr X-Ray: 50-100 CPM
300
A low battery indicator means this. (hint how hours of equip use are remaining)
What is the battery has less then 6 hrs remaining? (It operates off of two 9 volt batteries which can supply 200 hrs continuous use)
300
If directed by the Team Chief, to account for Radon, take ADM-300 alpha probe measurements at these two time intervals after the initial measurments.
What are 30 min and 4 hours?
400
The RADeCO is an outdoor all-weather instrument. (True or False)
What is false? (Limitation: Must be shielded from rain, must avoid contact with foam and liquids. Dusty environments may require frequent adjustments of the flow rate.)
400
You are surveying a crime scene and are in the process of identifying an isotope. In the spectrum you notice a magenta peak which indicates the presence of.....
What is special nuclear materials? (To interpret the screen, the class of the isotope, and the peaks and backscatter are abbreviated/color coded... Dark Blue IND = Industrial Magenta SNM = Spec Nuc Mat Light Blue MED = Medical Yellow UNC = Uncertain Green NRM = Naturally Occuring Rad Mat Red UNK = Unknown)
400
This decision happens after a technician reports the following ADM 300 results taken from the ECP: X-Ray Probe: Twice above background Alpha Probe: 500 CPM Beta/Gamma meter: 2 mR/hr
What is recommend ECP movement?
400
Operation in this mode gives the user a constant reference of the highest exposure rate obtained from the time the mode was initialized.
What is freeze mode? This equipment can operate in Integrate or Freeze Mode. Integrate means it operates continuously 30 sec after instrument has been turned on. Integration is performed even if the instrument is displaying in mR/h or R/h)
400
451P background readings should be collected at this type of location when the meter will be used outdoors during a response.
What is outside and/or outdoors? (Operators should obtain a background in an area that is upwind and similiar (indoors, outdoors, etc.) to the area of concern)
500
While operating the RADeCO, hearing protection is required. (True or False)
What is True?
500
During the identification process, you notice a yellow (UNC) peak. The best course of action to resolve this issue would be to.......
What is add an additional 30 seconds to the acquistion?
500
The initial reading for the 451P usually starts in this range and decreases through the lower ranges.
What is 5 R/hr?
500
Referring to these can almost always answer all "how-to" questions during a response.
