Uses of Thulium (Tm) in Everyday Life
From the Thulium page's study notes: Thulium (Tm) serves in alloys, infrastructure and the technologies of daily life. The full list, with Bangladesh examples, sits below.
Looking for Thulium's uses without wading through a whole chapter? Here is the direct answer first, then the tables and derivations examiners want to see. Every number on this page comes from the same engine that powers the interactive table. Need the whole picture instead — history, characteristics, uses, exam questions?

Thulium at work around you
Every use below comes straight from the full Thulium 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 Thulium in the study notes
- Thulium-170 portable X-ray sources — isotope capsules that emit penetrating rays with no electricity at all, serving field clinics, army medics and pipeline inspectors far from any power line.
- Thulium fibre lasers near 2 micrometres, whose water-hungry beam dusts urinary stones and trims prostate tissue with remarkably little bleeding.
- Industrial thulium fibre lasers for welding transparent plastics and precision-cutting where ordinary 1-micrometre beams pass straight through.
- Phosphor doping, including X-ray intensifying screens where Tm³⁺ turns invisible rays into visible light.
Where you meet it
- A mobile medical team X-raying patients in a riverine char village, far from the grid, can carry a thulium-170 capsule instead of a power-hungry machine.
- Urology departments advertising “no-scalpel” stone removal are increasingly reaching for thulium fibre lasers to do the job.

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