The 1st proton beam acceleration of the Linear IFMIF Prototype Accelerator (LIPAc) through its novel RFQ was succeeded on 13th June 2018. Addition to plenty of beam diagnostics equipped in the beam line, we prepared some radiation detectors placed around the accelerator in order to acquire supplemental information of the beam, as an indirect measurement. In the first day of the beam injec-tion to the RFQ, the gamma-rays corresponding to certain excited states of Al of the low power beam dump were successfully detected by a LaBr3(Ce) scintillation detec-tor. Some neutrons, which would originate from the inter-action of protons with Cu somewhere, were also ob-served. These results proved that the beam was certainly accelerated up to about 2.5 MeV, and provided us a defin-itive confidence that the RFQ was working appropriately from the very beginning of the commissioning. Also, the comparison of the radiation yields with the RFQ trans-mission provided additional information on the beam energy distribution.
