It should be noted that the manner in which the "microcontroller obtains the dose rate from the number of pulses and the amplitude" is well known to those skilled in the art, and therefore, the specific implementation thereof is not described too much.
For example, NaI scintillation detectors formulate the dose: moriuchi first proposed in 1971 to use the G (E) energy spectrum-dose conversion function to estimate the dose, i.e. adding different dose rate weight values to the counts of different energy channels, wherein the weight values are the G (E) function values of the energy channels. The method can calculate dosage more accuratelyAfter the functions G (E) are determined, corresponding dose can be obtained by direct field measurement, but the coefficients of the functions G (E) of different detectors are different and need to be respectively calibrated. The determination of G (E) has a direct influence on the calculation results. Wherein the air absorbent dose D (E) is determined by the following formula0)：
In the above formula, n (E, E)0) λ is a constant that is the probability that the detector will register a signal of E.
In practical application, an optimization algorithm is applied to simplify formula (1), and the simplified formula (1) is:
wherein D is the dose rate; dividing the maximum amplitude of the pulse into E parts, wherein the unit is track; the pulse analyzer and the microcontroller count the amplitude (i tracks) and the number (n) of the pulsesi)；G(E)iThe function is the dose rate weight value, which also varies for different pulse amplitudes (i track). But for a fixed volume detector, G (E)iThe function is a set of constants.
As another example, the use of G-M counters in dose measurement: as a sensitive radiation detector, G-M counters have been widely used, but the G-M counters respond to and absorb dose D, and the air kerma KαOr the dose X, is generally not directly related. However, if the material of the wall of the counter is properly selected or some shielding filtration is added outside the counter, the response of the G-M counter can be made proportional to the absorbed dose of air, the kerma of air or the irradiation dose in a certain energy range.
Setting a beam of X or gamma ray with photon energy of E to be incident on a G-M counter, wherein the photon fluence rate is
the irradiation dose rate at which the counter is located is assumed to be X; the mass energy absorption coefficient of X or gamma ray in air is (mu)en/ρ)αUnder the condition that the bremsstrahlung generated by the belt particles is negligible, the irradiation quantity X of a certain point in the air and the energy fluence of the pointRelation formula
G-M counters made of different cathode materials (Al, Cu and Pb) have detection efficiency almost proportional to photon energy within a certain energy range, namely η/E in formula (4)γApproximately a constant. And the mass energy absorption coefficient (mu) of gamma rays in the airen/ρ)αAnd the change is not large in a certain energy range. Thus equation (4) can be written as:
under the above conditions, k1, k2, and k3 are approximately constant, i.e., the irradiation dose rate, the air kerma rate, and the air absorption dose rate are approximately proportional to the counting rate of the counter. Thus, the measured counting rate can be used for determining the irradiation dose rate, the air kerma rate and the air absorption dose rate;
in the above formula, n is equivalent to the number of pulses of the electrical signal generated by the Geiger counter GM1 or GM2 counted by the microcontroller,
Further optionally, the signal analysis unit further includes: a display 10 embedded in the center of the upper plate 1 for displaying the dose rate acquired by the microcontroller.
