The present disclosure provides a smart terminal, including a radioactive detector, a communication device, an interactive device and a processor. The radioactivity detector is configured to detect a radioactive parameter and send a detection value of the radioactive parameter to the processor. The interactive device is configured to receive an operation instruction of a user and send the operation instruction to the processor. The communication device is configured to establish a connection and pair with a mobile terminal having a wireless communication function through a short range wireless communication mode. The processor is configured to establish a mapping between the interactive device of the smart terminal and an interactive device of the mobile terminal, and remotely control the interactive device of the mobile terminal according to the operation instruction received by the interactive device of the smart terminal.

A portable detection apparatus can include a housing, a first detector for detecting ionizing radiation from a first subject and a second detector within the housing for the detecting the background radiation. A shield within the housing can surround the first and second detectors and define a shield aperture around the first and second detectors for radiation from the subject to enter the housing. A radiation blocking member can substantially block at least a portion of the ionizing radiation from reaching the second detector, whereby radiation detected by the second detector comprises substantially only the background radiation. A processor module can be connected to the first and second detectors for determining the amount of ionizing radiation detected by the first detector attributable to secondary radiation.

A neutron detecting system and method. The neutron detecting system may include one or more coated substrates including a piezoelectric substrate having a first surface and a second surface opposite of the first surface, a coating of .sup.10boron (.sup.10B) on the first surface, and a conductive backplane deposited on the second surface. The coated substrates may be stacked to form a stacked layer array. When the neutrons are captured by the coating of .sup.10B on the coated substrates, energy will be released, causing crystal dislocation of the piezoelectric substrate, thus producing an electric signal through the conductive backplane of the coated substrates. The electric signal may be received with an amplifier to produce an amplified electric signal provided to a processor or circuitry. The processor or circuitry may send a notification signal to a visual or audible user interface indicating detection of the neutrons.
