Need help with datalogger from Arduino libraries

i have code log data sensors on sd library , have code geiger counter don't know how implement geiger code datalogger code.

the datalogger code

code: [select]

/*
  sd card datalogger

 this example shows how log data 3 analog sensors
 to sd card using sd library.

 the circuit:
 * analog sensors on analog ins 0, 1, , 2
 * sd card attached spi bus follows:
 ** mosi - pin 11
 ** miso - pin 12
 ** clk - pin 13
 ** cs - pin 4 (for mkrzero sd: sdcard_ss_pin)

    // don't more:

  // make string assembling data log:
  string datastring = "";

  // read 3 sensors , append string:

    int sensor = analogread(analogpin);
    datastring += string(sensor);
    if (analogpin < 2) {
      datastring += ",";

  }

  // open file. note 1 file can open @ time,
  // have close 1 before opening another.

  // if file available, write it:
  if (datafile) {
    datafile.println(datastring);
    datafile.close();
    // print serial port too:
    serial.println(datastring);

  // if file isn't open, pop error:

  serial.begin(9600);                                    // start serial monitor

 // uncommennt if have time-out problem connect radiation logger
 //  delay(2000);
 //  serial.write('0');                                      // sending 0 avoid connection time out radiation logger
