Element collecting from hydrogen to bismuth (except the radioactive technetium and promethium) are collected, with the exceptions of the extremely long-lived thorium and uranium. It is possible to source other radioactive elements, such as radium (usually in the form of radium sulphate as part of luminescent paint on antique watch hands), tritium - a radioactive isotope of hydrogen, americium (in the form of radioactive buttons containing 0.29 micrograms of americium extracted from older smoke detectors), and technetium. Element collecting Element collecting is the hobby of collecting the chemical elements. Many element collectors simply enjoy finding peculiar uses of chemical elements. Others enjoy
Uranium poisoning in Punjab early as 1995, Guru Nanak Dev University (GNDU) released a report, showing the presence of uranium and other heavy metals beyond permissible limits in water samples collected from Bathinda and Amritsar district, however there was no response from the government at that time. The hotspot for this increased toxicity, however was the Malwa region of Punjab, which showed extremely high levels of chemical, biological and radioactive toxicity, including uranium contamination. As the region's groundwater and food chain was gradually contaminated by industrial effluents flowing into fresh water sources used both for irrigation and drinking purposes, the region showed a rise
