In the laboratory, the samples were half-cleaned and dried first in 600C temperature during 168 hours. Then the homogeneous model by using a high speed blender has a blade made of titanium. Finally the model was added to the sample containers and be a flexible label. Can refer to the process in detail in Figure 2. The template is prepared for short projection mode, has a mass of ~ 50 mg, screened in the 300s in the irradiated 7.1 Channel has the neutron flux th = 4.1x1012n.cm2. s-1, =-9.8046, f = 0.0352, measured the isotopes 49Ca, 27Mg, 66Cu, 56Mn, 38Cl; the average projection and long mode has a mass of ~ 150 mg, premiered in 20 hours at the location of the irradiated alloy wheels are spinning neutron flux th = 7.7x1012n.cm2. s-1, = 0.091, f = 30.602, measured the isotopes 24Na, only 42 k, 59Fe, 60Co, 46Sc, 76As, 65Zn, 75Se, 86Rb, 134Cs, 203Hg. projection modes-half-measure for marine fish and freshwater fish samples are shown in table 1. Measure the gamma spectrum measurement system model has super high purity Germanium (HPGe) the relative performance of ~ 15-20% and energy resolution featured the 1.9 keV at 1332 keV energy of the isotope 60Co. Using the k0-the IAEA to handle gamma spectroscopy (computer content of the element) (4).
