Dosimeters detect and measure the cumulative ionizing radiation they see over time. Geiger counters detect the real-time flux of ionizing radiation at a specific location, and scintillators detect individual, real-time ionizing events and usually are constructed in a way to quantify variations in the ionizing energy.
Usually, dosimeters are placed on or near an at-risk individual for a length of time to measure their total exposure, while Geiger counters are used by rad-techs to determine how safe an experiment is or if a dangerous event is occurring. Scintillators are used almost exclusively by experimentalists to collect and sort data at high resolution.
A Geiger counter can be used to detect radioactive elements present in a mineral, such as uranium or thorium. The counter measures the level of radioactivity emitted by the mineral by detecting the high-energy particles produced by radioactive decay.
A tsunami detection buoy is one of the primary instruments used to detect tsunamis. These buoys are equipped with sensors that can detect changes in water pressure caused by a tsunami wave passing overhead. The data collected by these buoys is then transmitted to monitoring stations to provide early warnings.
A tonometer is the medical term for the instrument used to measure the pressure in the eye to detect glaucoma. The tonometer shoots a blast of air into the eye, directly into the pupil.A tonometer is used to measure eye pressure.
An ammeter is commonly used to detect electron flow in a circuit. The ammeter measures the amount of current (flow of electrons) passing through a specific point in the circuit.
Radioactive tracers in pipes can come from various sources such as leakages from nuclear facilities, medical facilities that use radioactive materials for treatments, or industrial processes that involve radioactive isotopes. These tracers are used to detect leaks, blockages, or flow patterns in pipes.
The explorer is used by the dentist to detect decay.
An electroscope is the instrument used to detect static charge. It consists of a metal-leaf or needle that responds to the presence of electric charge by diverging from its equilibrium position.

A Geiger-Muller counter is the instrument used to detect radioactivity by measuring ionizing radiation levels.
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.
A Geiger counter can be used to detect radioactive elements present in a mineral, such as uranium or thorium. The counter measures the level of radioactivity emitted by the mineral by detecting the high-energy particles produced by radioactive decay.

A Geiger counter is commonly used to detect radiation. It detects ionizing radiation by measuring the levels of radiation in the environment and producing audible clicks or visual displays to indicate the presence of radiation.

Seismometer (or seismograph) and it measure seismic waves
Often times doctors will inject radioactive dye into the blood and then scan for the radiation. It allows doctors to detect where the bloodstream is taking the isotope, which in turn allows them to search for issues in circulation. Think of it as equivalent to dropping a GPS beacon into a river to detect where the water is ending up.
A sound level meter is typically used to detect noise. It measures the intensity (loudness) of sound in decibels (dB) to quantify noise levels in different environments.
