Development of a number of promising photonuclear technologies is connected with the use of bremsstrahlung sources having end-point energy up to 100 MeV and average radiation power of tens kW. Commonly, such sources are created on the basis of high-current electron linacs. A possibility of bremsstrahlung dosimetry by means of activation of a target from indium of natural composition and absorbed dose determination through the specific activity of the 115mIn isomer is reported. Preliminary study of isomer photoactivation as well as the yield of reference reactions from simultaneously irradiated natural molybdenum was conducted by simulation technique. Joint measurement of the 115mIn, 90Mo, 99Mo activity and absorbed dose in the PMMA standard dosimeters were carried out at LU-10 and LU-40 linacs of NSC KIPT in the electron energy range 8…70 MeV. It was found that, within the range of study, the ratio of the 115mIn specific activity to absorbed dose in the PMMA slightly depends on the bremsstrahlung end-point energy.

The system for visual monitoring of the electron beam features was developed and implemented. This system is based on registration of optical radiation, which is generated under object-beam interaction. The system comprises image transferring channel, remote-controlled digital photo-camera, connected with PC by USB-interface as well as proper software. The images obtained give information on the beam density distribution over the surface of the object being irradiated. 100 KeV and 10 MeV electron beams was researched.
