Description：
|
When a gamma ray enters into the NaI crystal, the photo multiplier outputs a pulse with amplitude proportional to gamma ray energy absorbed by NaI crystal. It adopts spectrum stabilization technology to set up windows with different energies. The counting rate of each energy window is sent to the surface system by electronic circuits. After processed by surface system, Th, U and K contents are calculated out.

FUNCTIONCOMPOSITIONTECHNICAL SPECIFICATIONSFILED EXAMPLE
When a gamma ray enters into the NaI
crystal, the photo multiplier outputs a pulse with amplitude proportional to
gamma ray energy absorbed by NaI crystal. It adopts spectrum stabilization
technology to set up windows with different energies. The counting rate of each
energy window is sent to the surface system by electronic circuits. After
processed by surface system, Th, U and K contents are calculated out.
It owns independent IP address and communicates with
telemetry / GR tool by Ethernet, which can receive the command, and send
digital signal to telemetry /GR tool. It can offer the total amount of natural
gamma ray and amount of Th, U and K. This data is sent to surface system with 256
channels full spectrum technology.
It
is composed of electronic cartridge, sonde and housing with material of precipitation
hardening stainless steel.
