Uranium glass was made into tableware and household items, but fell out of widespread use when the availability of uranium to most industries was sharply curtailed during the Cold War in the 1940s to 1990s, with the vast majority of the world's uranium supply being utilised as a strategic material for use in nuclear weapons or nuclear power.
These particles excite the phosphor, causing it to emit a low, steady glow. Tritium is not the only material that can be used for self-powered lighting. Radium was used to make self-luminous paint from the early 20th century to about 1970. Promethium briefly replaced radium as a radiation source. Tritium is the only radiation source used in ...
A 380 nanometer UV LED makes some common household items fluoresce. Light-emitting diodes (LEDs) can be manufactured to emit radiation in the ultraviolet range. In 2019, following significant advances over the preceding five years, UVA LEDs of 365 nm and longer wavelength were available, with efficiencies of 50% at 1.0 W output.
Technically, microwaves do emit “electromagnetic radiation,” but according to Dr. Arya Amini, associate professor and chief of thoracic radiotherapy at the City of Hope National Medical Center ...
Americium-241 is the only synthetic isotope to have found its way into the household, where the most common type of smoke detector (the ionization-type) uses 241 Am O 2 (americium-241 dioxide) as its source of ionizing radiation. [11] This isotope is preferred over 226 Ra
The devices emit low levels of radiation, but they pose no health risks to users.
An open (single envelope) CFL [12] An encapsulated/closed (double envelope) CFL. Some fluorescent lamps emit ultraviolet radiation. [citation needed] The Health Protection Agency of the United Kingdom has conducted research concluding that exposure to open (single envelope) compact fluorescent lamps (CFLs) for over 1 hour per day at a distance of less than 30 cm can exceed guideline levels as ...
