 First set of measurements was done using only NLaK sample placing it in the centre of the X-Ray setup shelf, directly under the source. That allows to be sure about the dose rate.

Dose for 7.5 s using dosimeter on shelve 8 was measured to be 81.4 R, so for NLaK it should be ~25R.

We use X-Ray setup with 160 keV and 6.2 mA. Dose collected over 7.5 s using dosimeter on shelve 8 was measured to be 81.4 R, so for NLaK it should be ~25R.
 We used monochromator to quantify influence of irradiation by measuring transmission. We also had Fused Silica plate used as reference to normalize NLaK measurements. Below one can see that the beam of monochromator nicely fits in samples.
