Revision March 2017 GAMMA EMITTING RADIONUCLIDES Test Description Determination of gamma photons emitted from radionuclides. Test Use Useful for evaluating water, milk, sediments, solid media, fish, vegetation, wipes, and air samples collected on charcoal cartridges and filters. Test Department Radioc hemistry: Phone 860 - 920 - 666 8/6669 Fax 860 - 920 - 6 670 Methodology EPA Method 901.1: Gamma Spectroscopy Availability Year - round Sample Requirements For Liquid Samples: One (1) sample collected in a pre - cleaned plastic or glass Chem Bottle. One (1) Field Blank per collection trip Container type /Preservative For liquid samples: ½ gallon plastic or glass Chem Bottle No Preservative Collection Instructions (Note 1) For taps, remove aerators and let water run 4 - 5 minutes. For outdoor locations, sampling location should be in accordance with a preapproved quality assurance project plan. Sample Holding Time & Transport Samples must be received by the lab within 5 days of collection . Unacceptable Condi tions Incomplete requisition form. Insufficient sample volume. Samples received beyond the 5 - day holding time. Requisition Form Use the Organic/Radiation Chemistry requisition form . Required Information Fill out entire requisition form. Limitations Samples to be tested for Iodine - 131( 131 I) will be rejected if received by the lab more than 5 days after collection. Samples to be tested for other radionuclides may be analyzed up to a holding time of 6 months if they have been acidified either in the fie ld or at the laboratory within 5 days of collection. Additional Comments The CT PHL is capable of reporting a wide range of photon emitters with this method.
