1. Static yekuona kunyatsoita (AB)
A. Static monitoring performance yevanofamba netsoka
| radioactive source | Simba gurukeV | Static yekuona kunyatsoshanda | Dose rate pa1.5m / (nSv.h-1/MBq | |
| s-1/MBq | s-1/(nSv.h-1) | |||

kudurura:
1. Iyo 252Cf neutron yakajairwa bvunzo sosi ine yakasimba neutron sosi ye12000 / s (1 ± 20%) inoiswa panzvimbo ye detector reference point.
2. Chiyero chekuverengera neutron chichasangana nezvinodiwa zvehuwandu hwehuwandu hwe> 100 (1 ± 20%) / s.
Static yekuona kugona kweiyo B-row pasuru yekutarisa system

2. Kuziva kunzwa
Pedestrian monitoring system uye mutsara wepasuru yekutarisa system
Vanofamba netsoka: Mikana yekuona f 90% kumhanya v=1.2m/s
Mutsara pasuru: probability f 90% kumhanya v=1m/s
| radioactive source | Chiitiko kana kunaka |
| 137Cs | 0.08MBq |
| 60Co | 0.02MBq |
| 241Am | 2.27MBq |
3. Anti-kupindira kushanda kweneutron detector
Kana iyo 60Co sosi ichigadzira chiyero chedosi panzvimbo yejometri yeneutron detector pamusoro peiyo yekutarisa system, yakakura kupfuura 120 Sv / h, iyo yekutarisa system haifanirwe kukonzeresa neutron alarm.
4. Kunyepa kwearamu mwero: 0.01% (, neutron)
Mikana yearamu yekuona system inokonzerwa neasina-radioactive zvinhu kana asiri-SNM
5. overload maitiro
Kana iyo detector yepamusoro dosi chiyero ichi> 120 Sv / h, iyo yekutarisa sisitimu inochengetedza iyo alarm mamiriro uye kudzokera kumamiriro ekumashure, uye nguva yekuburitsa alarm isingasviki makumi matanhatu.
6. Sensitivity kuenderana
Mukati mehuwandu hwenzvimbo yekuona
Vanofamba netsoka ± 25% Mutsetse Paki ± 25%
Misalarm rate
Munzvimbo yakagadzikana:
Shandisa iyo space sensor, 10000 nguva, yenhema alarm rate 1
Pasina kushandisa iyo inogara sensor, iyo yenhema alarm rate uye misidentification rate inoshandiswa kamwe mukati me12h
γ Mhinduro yeRadiation
Kutora ka50 nguva, alarm 49 nguva
Hasha
Pamusoro pe100 v S / h, yakakwira radiation alarm inoburitswa uye inobviswa mukati me1min mushure mekubva
Radiation-induced neutron alarm
Hapana neutron alarm inokonzereswa kana chiyero cheiyo γ-ray chasvika 100 Sv / h.
Kufurira kumashure
Kana shanduko yekumashure yakakurisa zvekukonzeresa shanduko huru mumukana wealarm, iyo yekutarisa system ichaburitsa yambiro yekukasira.
