Title:
NONCONTACT CARGO DETECTOR
Document Type and Number:
WIPO Patent Application WO/2004/048951
Kind Code:
A1
Abstract:
A small chemical substance detector capable of detecting, by transmitting a radio wave, the NQR of an atom contained in a chemical substance using a high-temperature superconducting SQUID magnetic sensor exhibiting a high sensitivity even to a low frequency without unsealing the chemical substance contained in a package or a container. The chemical substance capable of being detected at the same time.
