Henri Becquerel discovered radiation in 1896 while working with uranium salts. His serendipitous discovery of radioactivity paved the way for further research and development of methods to detect and measure radiation.
The ocean,the mountains,the air and our food all expose us to small ammounts of natural radiation.
Emmett W. Chappelle invented a way to detect life on other planets using bioluminescence, a chemical reaction that produces light in living organisms. He also developed methods to detect pollutants in the environment and improve the productivity of plants.

You can't use spectrometers to detect black holes. Telescopes are the only way to detect them.
Generally, photons are very easy to detect. Your eyes do a good job of detecting photons within a certain frequency band, as photons constitute light and other electromagnetic radiation. Individual photons are impossible to detect with modern technology.
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 only sure-fire way to detect a gay man is to ask him.
Visible radiation (a.k.a. light) is the wavelengths we can see. Infrared radiation lies down below the red end of the spectrum that we can see, hence infra red. But we can make device that both generate and detect infra red radiation. Your TV control works this way.
