The principle of operation is based on measure ment of the activity of samples previously taken from the water or air in the measuring cell with special film scintillators or in liquid scintillat ors vessels. The device is designed for the control of tritium in enterpri ses associated with the use\, receipt or processing of tritium\, as well a s for environmental monitoring. The device can be used in the work of the personnel radiation monitoring service\, health care\, environmental prote ction and other organizations that solve similar problems monitoring of tr itium in samples of air or water.\n\nhttps://indico.particle.mephi.ru/even t/2/contributions/456/ LOCATION:Milan Hotel 4* Bellini URL:https://indico.particle.mephi.ru/event/2/contributions/456/ END:VEVENT BEGIN:VEVENT SUMMARY:Measurement of Radon concentration by Xenon gamma-ray spectrometer for seismic monitoring of the Earth DTSTART;VALUE=DATE-TIME:20151007T110000Z DTEND;VALUE=DATE-TIME:20151007T111500Z DTSTAMP;VALUE=DATE-TIME:20260423T040443Z UID:indico-contribution-58-422@cern.ch DESCRIPTION:Speakers: Alexander Novikov (NRNU MEPhI)\nA method for earthqu ake precursors search based on variations of 222Rn concentration determine d via intensity measurement of 222Rn daughter nuclei gamma ray emission li nes by means of xenon gamma-ray spectrometer is discussed.

This determines the choice of material. So for protec tion from magnetic fields strength of 10 - 150 A/m is advisable to apply t he amorphous ribbon 84KXCP. For stronger fields (more than 400 A/m) multil ayer film shields based on Ni20Fe80 should be used. Using these materials allows creating an effective shield working in a wide range of magnetic fi eld strengths.\n\nhttps://indico.particle.mephi.ru/event/2/contributions/4 18/ LOCATION:Milan Hotel 4* Bellini URL:https://indico.particle.mephi.ru/event/2/contributions/418/ END:VEVENT BEGIN:VEVENT SUMMARY:Performances investigation and material selection of PMT magnetic shields for the space experiments with GRIS and PING-M instruments DTSTART;VALUE=DATE-TIME:20151007T103000Z DTEND;VALUE=DATE-TIME:20151007T104500Z DTSTAMP;VALUE=DATE-TIME:20260423T040443Z UID:indico-contribution-58-401@cern.ch DESCRIPTION:Speakers: Rodion Faradzhaev (National Research Nuclear Univers ity MEPhI)\nScintillation detectors based on Hamamatsu photomultiplier tub es (PMTs) R6233-100 and R6231-100 with diameter of photocathode 76 mm and 51 mm respectively are used in GRIS experiment\, which is planned to be in stalled onboard the ISS\, and in PING-M for Interhelioprobe mission. PMT p erformances significantly change under the influence of a magnetic field. Even the relatively weak geomagnetic field\, which typically value is abou t 0.5 gauss\, has an appreciable effect. PMT gain variations with photocat hode diameter 76 mm may reach 10-20 % depending on spatial orientation. Th erefore\, it is necessary to apply magnetic shields for PMT response stabi lity enhancement.\n The performances investigation of magnetic shields ma de of steel\, permalloy and amorphous metallic alloy ribbon was carried ou t. Influence of the shield position relative to the PMT photocathode was s tudied. Based on obtained data the choice of magnetic shield was made.\n\n https://indico.particle.mephi.ru/event/2/contributions/401/ LOCATION:Milan Hotel 4* Bellini URL:https://indico.particle.mephi.ru/event/2/contributions/401/ END:VEVENT BEGIN:VEVENT SUMMARY:Effectiveness of protection from low frequency electromagnetic rad iation by multilayered film structures DTSTART;VALUE=DATE-TIME:20151007T101500Z DTEND;VALUE=DATE-TIME:20151007T103000Z DTSTAMP;VALUE=DATE-TIME:20260423T040443Z UID:indico-contribution-58-372@cern.ch DESCRIPTION:Speakers: Sergei Grabchikov (Scientific-Practical Materials Re search Center\, National Academy of Sciences of Belarus)\nThe problem of e lectronic and scientific equipment protection becomes more actual nowadays . Protection from low-frequency electromagnetic radiation (LF EMR) is the most complicated case of electromagnetic shielding.\nThe results of the sh ielding efficiency from LF EMR by multilayer film shields based on permall oy / copper systems\, depending on their internal structure\, the paramete rs of the EMR\, as well as some examples of practical application are pres ented.\n\nhttps://indico.particle.mephi.ru/event/2/contributions/372/ LOCATION:Milan Hotel 4* Bellini URL:https://indico.particle.mephi.ru/event/2/contributions/372/ END:VEVENT END:VCALENDAR
