The count rate observed by a Geiger counter is proportional to activity, not to half-life.

Geiger Counter
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.
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.
The principle of a Geiger-Muller counter is based on detecting ionizing radiation by counting the number of electrical pulses produced when radiation interacts with a gas inside the detector. The ionizing radiation creates ion pairs in the gas, which are then accelerated by an electric field, resulting in a measurable pulse of current that is counted and used to determine the level of radiation. This technique allows for the detection of various types of ionizing radiation, such as alpha, beta, and gamma radiation.
The Geiger counter is a tool that was invented to measure radioactive materials for safety purposes. Factors that can prevent the Geiger counter from providing accurate results include failure to calibrate the tool before use, indirect readings that fail to locate hidden radioactive rays, and a low battery.

Geiger counter.
This device is called a Geiger Counter, or sometimes a Geiger-Muller counter, which measures alpha particle concentration. It was developed by Hans Geiger and Walther Muller in the early 1900's.
Radioactive materials are substances that contain unstable nuclei that can undergo radioactive decay, releasing energy in the form of radiation. Common examples include uranium, plutonium, and radium.
