Curie’s work on radium and polonium not only won her two Nobel Prizes but also spurred further scientific inquiry into radioactivity. Geiger’s development of the Geiger-Müller counter in the 1920s marked a significant milestone in detection technology. This device was designed to measure ionizing radiation and quickly became the standard for radiation measurement in laboratories and fieldwork.
As the decades progressed, advancements in technology led to the creation of increasingly sophisticated instruments. Scintillation detectors, which use crystals that emit light when exposed to radiation, became widely utilized for their sensitivity and ability to detect lower levels of radiation. Semiconductor detectors followed, utilizing materials like silicon and germanium to provide even greater precision. The introduction of portable gamma-ray spectrometers allowed for on-site analysis, making it easier to detect and characterize radioactive materials in various environments, from laboratories to potential incident sites.
The evolution of these instruments has been propelled by both scientific advancements and the pressing need for enhanced security measures, particularly in the wake of historical events that raised awareness about nuclear threats. The post-Cold War era, for instance, saw a notable increase in the focus on nuclear security as nations recognized the potential for nuclear materials to fall into the hands of unauthorized individuals or terrorist organizations. This led to the establishment of international frameworks designed to mitigate these risks, such as the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) and various initiatives led by the IAEA, which advocate for the safe and peaceful use of nuclear technology while preventing proliferation.
