A thermoluminescent dosimeter (TLD) A thermoluminescent dosimeter, or TLD, is a type of radiation dosimeter, consisting of a piece of a thermoluminescent crystalline material inside a radiolucent package. When a thermoluminescent crystal is exposed to ionizing radiation, it absorbs and traps some of the energy of the radiation in its crystal ...
This list of Internet top-level domains (TLD) contains top-level domains, which are those domains in the DNS root zone of the Domain Name System of the Internet. A list of the top-level domains by the Internet Assigned Numbers Authority (IANA) is maintained at the Root Zone Database. [ 1 ]
A top-level domain (TLD) is one of the domains at the highest level in the hierarchical Domain Name System of the Internet after the root domain. [1] The top-level domain names are installed in the root zone of the name space.
A top-level domain (TLD) is a highest-level Internet domain name. TLD or tld may also refer to: Telefónica Larga Distancia, Telefónica's Puerto Rican telecomms subsidiary; Thermoluminescent dosimeter, measuring radioactivity; Tuli Lodge Airport, Botswana, by IATA code; TLD, a manufacturer of Ground support equipment.
However, the creation of the .uk TLD predates the ISO 3166-1 list of ccTLDs and is the primary TLD for the United Kingdom.

ICANN re-opened the TLD Application System on May 21, allowing applicants to submit and review their applications until May 30, 2012. [26] On "Reveal Day" June 13, 2012, it was announced that ICANN received about 1,930 applications for new gTLDs, 751 of which were contested. [27] It was expected for the new gTLDs to go live in June 2013.
However, these have been mostly superseded by thermoluminescent dosimetry (TLD) badges and electronic dosimeters. Electronic dosimeters can give an alarm warning if a preset dose threshold has been reached, enabling safer working in potentially higher radiation levels, where the received dose must be continually monitored.
