Handled by the data measured to detector (100,100 '), can be stored in advance in determination unit (231,
231 ') in.The measurement result may include conversion coefficient between measured energy and amplitude, at least two amplitudes and right
The energy or record answered have the look-up table etc. of the matching relationship between amplitude and energy.It should be noted that for different
Detection channels, above-mentioned measurement result can be not quite similar, that is, partly or entirely different.
Under normal conditions, it is between the amplitude of electric signal and the energy corresponding to it of detector (100,100 ') output
Linear relationship, which can be expressed by following formula: M=k*E+b, wherein M indicates amplitude, and E indicates energy
Amount, k and b indicate conversion coefficient.The two conversion coefficients k and b can by the power spectrum to the reference electrical signal measured in advance into
Row handles to obtain.Specifically, amplitude (for example, voltage or electric current etc.) can be extracted from the power spectrum measured, then root
According to the energy of the amplitude and used radiation source that are extracted, linear relationship between the two is determined, so that it is determined that out two
Conversion coefficient between person.
The case where for above-mentioned conversion coefficient is stored with, after receiving energy threshold, determination unit (231,231 ')
It can use stored conversion coefficient to calculate energy threshold, so that it is determined that corresponding amplitude threshold out.
Alternatively, it is also possible to directly by the amplitude extracted from the power spectrum of the reference electrical signal measured and used radiation
The energy in source is stored in determination unit (231,231 ') as measurement result, in this way, determining after receiving energy threshold
Unit (231,231 ') can determine corresponding amplitude threshold by carrying out linear difference to measurement result using energy threshold
Value.
In addition, the case where between amplitude and energy at non-linear conversion relationship, it can be according to used radiation source
Energy and measured reference electrical signal amplitude construct look-up table, the look-up table is then stored in determination unit
In (231,231 ').In this way, determination unit (231,231 ') can be from the look-up table stored after receiving energy threshold
In find out and the matched amplitude threshold of energy threshold.
By taking counting channel 200 as an example, it can operate as follows: after receiving externally input energy threshold, conversion
Determination unit 231 in unit 230 can be determined received with institute according to the measurement result of the reference electrical signal of storage inside
The corresponding amplitude threshold of energy threshold, the amplitude threshold is digital signal at this time, and then digital analog converter 232 will determine single
The digital signal that member 231 is sent is converted to analog signal and the analog signal after conversion is supplied to comparator 210；It is receiving
After the analog signal that the electric signal to be measured and converting unit 230 that detector 100 exports are sent, comparator 210 is to both letters
Number amplitude be compared, when compare electric signal to be measured amplitude be greater than or equal to analog signal amplitude when, comparator 210
High level can be exported to counter 220, when the amplitude for comparing electric signal to be measured is less than the amplitude of analog signal, comparator
210 export low level to counter 220；After the level signal for receiving the transmission of comparator 210, counter 220 can be opened
Beginning is counted, and when level signal is high level, 1 can be added on the basis of initial count (for example, 0), until reaching
Its count upper-limit, and when level signal is low level, initial count is maintained, until receiving high level.It completes to count
Later, counter 220 can be output to the outside recorded enumeration data.
