Low-level waste
nuclear waste that does not fit into definitions for intermediate-level and high-level waste
Low-level waste (LLW) or low-level radioactive waste (LLRW) is a category of nuclear waste. The definition of low-level waste is set by the nuclear regulators of individual countries, though the International Atomic Energy Agency (IAEA) provides recommendations.
LLW includes items that have become contaminated with radioactive material or have become radioactive through exposure to neutron radiation. This waste typically consists of contaminated protective shoe covers and clothing, wiping rags, mops, filters, reactor water treatment residues, equipments and tools, luminous dials, medical tubes, swabs, injection needles, syringes, and laboratory animal carcasses and tissues.
LLW in the United Kingdom
In the UK, LLW is defined as waste with specific activities below 12 gigabecquerel/tonne (GBq/t) beta/gamma and below 4 GBq/t alpha emitting nuclides. Waste with specific activities above these thresholds are categorised as either Intermediate-level waste (ILW) or high heat generating waste depending upon the heat output of the waste.
Very Low Level Waste (VLLW) is a sub-category of LLW. VLLW is LLW that is suitable disposal with regular household or industrial waste at specially permitted landfill facilities. The major components of VLLW from nuclear sites are building rubble, soil and steel items. These arise from the dismantling and demolition of nuclear reactors and facilities.
LLW in the United States
LLW in the United States is defined as nuclear waste that does not fit into the categorical definitions: high-level waste (HLW), spent nuclear fuel (SNF), transuranic waste (TRU), or certain byproduct materials known as 11e(2) wastes, such as uranium mill tailings.
The public source identifies “Low-level waste” as nuclear waste that does not fit into definitions for intermediate-level and high-level waste. This brief keeps that definition visible, then builds a research path around Low-level, waste and nuclear.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Low-level waste”, the useful work is to connect “nuclear waste that does not fit into definitions for intermediate-level and high-level waste” to the records capable of establishing context and consequence.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Sep 3, 2026. The linked authority identifier is Q6692765. None of the 0 selected statements returned an explicit reference.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
