Uses of Plutonium (Pu) in Everyday Life
From the Plutonium page's study notes: Plutonium (Pu) serves in alloys, infrastructure and the technologies of daily life. The full list, with Bangladesh examples, sits below.
This is the fast lane: one page, one fact, zero digressions. Read the quick answer, check the table, and if your exam needs the full derivation, the sections below walk through it step by step — in Bangla and English, like every page here. Need the whole picture instead — history, characteristics, uses, exam questions? The full Plutonium page is one click away.
Plutonium at work around you
Every use below comes straight from the full Plutonium study page, where each point also carries the chemistry behind it and an exam-style question. Skim the list here; open the full page when revision time comes.
Uses of Plutonium in the study notes
- Space batteries (RTGs): plutonium-238’s tireless heat turns into electricity aboard Voyager 1 and 2 — still calling home after more than 45 years — and powered New Horizons, which flew past Pluto in 2015 on plutonium’s own namesake.
- Mars rovers: Curiosity and Perseverance carry Multi-Mission RTGs, so plutonium keeps their cameras and drills alive through the dust storms that starve solar panels.
- MOX fuel: mixed-oxide pellets of and burn surplus weapons plutonium in power reactors — swords melted into kilowatt-hours in France, Belgium and Japan.
- Nuclear weapons: Pu-239 cores triggered by implosion — the Nagasaki bomb and most of the world’s arsenals ever since.
- A medical curiosity: a few score plutonium-238 pacemakers fitted in the 1970s still tick inside elderly patients, never once needing a new battery.
Where you meet it
- When the news reports that Voyager still transmits from interstellar space, the signal’s electricity is Pu-238 heat — the element’s gentlest job.
- New Horizons’ 2015 Pluto flyby handed physics teachers a perfect line: a plutonium-powered craft visiting Pluto.
- Every 9 August the world remembers Nagasaki — history’s second atomic bomb and its first plutonium one — and museum exhibits retell how the metal was born in secret.

Why is Plutonium important in Bangladesh?
The full study page connects Plutonium to Bangladeshi life — school labs, local industries, health and the NCTB syllabus. This quick-answer page is the fast summary; the element page is the full story.
Where will I meet Plutonium in the NCTB exam?
Questions on Plutonium's uses are a recurring pattern in Class 9–10 and HSC chemistry. The element page ends with six exam-style questions in both languages — practise those and this pattern stops costing marks.
