Uses of Radium (Ra) in Everyday Life
From the Radium page's study notes: Radium (Ra) 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.

Radium at work around you
Every use below comes straight from the full Radium 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 Radium in the study notes
- Luminous paint: radium mixed with zinc sulfide brushed the glow onto watch, clock and aircraft dials from the 1910s — until the slow deaths of the dial-painting “radium girls” spelled the beginning of the end of the trade.
- Early cancer therapy: sealed radium needles and tubes were implanted beside tumours — “Curie therapy”, the ancestor of modern brachytherapy — before cobalt-60 took over the job.
- Historic quack medicine: tonics like Radithor, “certified radioactive water”, sold glowing health until the 1932 death of steel heir Eben Byers forced regulation.
- Modern medicine’s careful return: the isotope radium-223 (trade name Xofigo) is an approved drug that mimics calcium to home in on prostate-cancer bone metastases, turning the old poison into precision therapy.
Where you meet it
- A grandparent’s glow-in-the-dark watch from the 1950s may still faintly shine — antique dealers warn collectors never to open the dial.
- Marie Curie’s century-old laboratory notebooks are stored in lead boxes at the French national library; readers must sign a health waiver.
- Every uranium ore carries radium through the decay chain — and the Curies’ tonnes-to-a-tenth-of-a-gram shed story is retold in Bangladeshi classrooms whenever radioactivity is taught.

Why is Radium important in Bangladesh?
The full study page connects Radium 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 Radium in the NCTB exam?
Questions on Radium'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.
