Nuclear radiation detection device for use in key chain for detection of gamma and beta particles during disaster at nuclear power plant, has detection system including semiconductor diodes, charge amplifier and discriminator

摘要

The device has a detection system (100) including semiconductor diodes (101), a charge amplifier (106) consuming less than 20 micro ampere, and a discriminator (111) having very low power consumption. An electronic processing unit includes a microprocessor, a quartz clocked at less than 50 KHz, an LED and a buzzer, where the device is powered by a power supply including a rechargeable battery, a solar panel and/or a universal serial bus (USB)port. An independent claim is also included for a device for fixing an electronic card.
