flux meter
Helium is generally used; special spectrometers to detect helium leakage are designed.

Devices such as Geiger counters, scintillation detectors, and ionization chambers are commonly used to detect radioactivity. These devices can detect the presence and measure the strength of radiation from radioactive materials.
This ndt method is used for the detection of surface an near to surface discontinuities in ferromagnetic materials,by applying a magnetic field and a medium sensitive to areas of magnetic flux leakage.This medium will be attracted,and held,to the part surface(by the flux leakage)and the visual indication of a discontinuity then interpreted by a qualified operator.
Earth leakage units (ELUs) refer to the measurement of electrical current that leaks from a circuit to the ground, which can indicate potential safety hazards. They are often used in the context of electrical installations to assess the integrity of insulation and to detect faults that could lead to electric shocks or fires. ELUs are typically monitored by devices such as residual current devices (RCDs), which help protect users by disconnecting the power supply when leakage is detected above a certain threshold.
this type of transformer used special low loss steel to minimize eddy current losses and reduced leakage flux.
Smoke detectors are devices that detect smoke. They are used as warning devices in houses to warn people of fire.
Laser-ranging devices us laser beams to detect the fault movements that cause earthquakes.
No, these devices do not cause cancer or they would not be used in hospitals. They can detect cancer and are also used on pregnancy so they do not cause cancer!
