Description:
        Data items in the DIFFRN_RADIATION category describe
               the radiation used for measuring diffraction intensities,
               its collimation and monochromatization before the sample.
               Post-sample treatment of the beam is described by data
               items in the DIFFRN_DETECTOR category.
Examples:| Example 1 - based on PDB entry 5HVP and laboratory records for the
                structure corresponding to PDB entry 5HVP 
 
    _diffrn_radiation.diffrn_id            'set1'
    _diffrn_radiation.collimation          '0.3 mm double pinhole'
    _diffrn_radiation.monochromator        'graphite'
    _diffrn_radiation.type                 'Cu K\a'
    _diffrn_radiation.wavelength_id         1

| Example 2 - based on data set TOZ of Willis, Beckwith & Tozer
                [Acta Cryst. (1991), C47, 2276-2277]. 
 
    _diffrn_radiation.wavelength_id    1
    _diffrn_radiation.type             'Cu K\a'
    _diffrn_radiation.monochromator    'graphite'
