[accompanying drawing explanation]
Fig. 1 is the schematic diagram of portable multi-function digital radiation logging of the present utility model.
[embodiment]
Refer to shown in Figure of description 1, the utility model is a kind of portable multi-function digital radiation logging, and it is by sodium iodide probe 1, lanthanum bromide probe 2, Geiger counter tube 3, plastic scintillant probe 4, BF
3a few part composition such as probe 5, multichannel analyzer 6, PDA7 and host computer 8.
Wherein, described sodium iodide probe 1, lanthanum bromide probe 2, Geiger counter tube 3, plastic scintillant probe 4, BF
3probe 5 is connected on multichannel analyzer 6 respectively.These probes are used to a gamma-rays, x-ray, alpha ray, β ray, neutron ray etc. and become electric signal.Wherein, sodium iodide probe is mainly used to measure gamma-rays and x-ray, good resolution in 8%, according to efficiency difference have 3 inches, 2 inches, 1.5 inches optional.Lanthanum bromide probe is mainly used to measure gamma-rays and x-ray, good resolution in 3.8%, according to the difference of resolution have 2 inches, 1.5 inches, 1 inch optional.Geiger counter tube (GM pipe) is used for measuring high dose gamma-rays and x-ray.Plastic scintillant probe is mainly used to measure alpha ray and β ray.BF
3probe is mainly used to measure neutron ray.
Described multichannel analyzer 6 is connected to PDA7 and host computer 8 respectively, and it is used for the electric signal of probe conversion to become modal data.The energy of radioactive particle is directly proportional with the quantity of electric charge produced in probe, and then is directly proportional to the voltage of electric signal.The radioactive intensity of radioactive particle is directly proportional to the number of signals detected in the probe unit interval.The basic effect of signal acquiring system will measure energy and the quantity of radioactive particle, i.e. power spectrum exactly accurately.The horizontal ordinate of described multichannel analyzer 6 is location, represents the energy of radioactive particle, and ordinate is counting rate, represents the intensity of radioactive particle.Multichannel analyzer is equivalent to one and measures the ruler of particle energy, and the quality of ruler is crucial in three, and one is the segmentation degree of scale, also just certain energy range is segmented how many parts; Two is degree of uniformity of scale, and general differential linearity and integral linearity are weighed; Three is average counter rates, and average counter rate is higher, illustrates that the time of measuring single particle needs is fewer, can survey the radioactivity that intensity is higher.
Described multichannel analyzer 6 is connected to PDA by bluetooth, is connected to host computer by USB or Ethernet.Specifically, after multichannel analyzer 6 becomes radioactive particle information into modal data, adopt PDA6 to show, data are transferred to PDA through bluetooth radio module.Simultaneously, conveniently professional person carries out process and the analysis of modal data, portable multi-function digital radiation logging of the present utility model can also be transferred to host computer through dedicated ethernet interface or USB interface data, by professional software Treatment Analysis modal data.
