Uses of Nuclear Radiation - GCSE Physics - Summary
Показать описание
Radiation is used in medicine to:
Explore internal organs.
Control or destroy unwanted tissue.
Gamma emitters can be injected into the blood and a gamma camera outside of the body can detect the location of the gamma emitter.
This is especially useful for analysing rates of blood flow for people with circulation problems.
We can also use radioactive iodine to analyse fluid flow in the kidneys.
A tracer needs to be a gamma emitter to be detected outside the body, and needs to be a long enough half-life to run the test, but short enough to limit the risk.
Gamma radiation can be used to kill cells in cancerous tumours. A narrow beam from a cobalt source is focussed on the tumour. It is rotated around the body so that the healthy cells get a small dose of radiation and the cancerous cells get a large dose. It has to be gamma to penetrate into the body.
We can also use beta or gamma releasing implants placed next to a tumour, this gives a continuous dose to the tumour but has a short enough half-life so that it is not radioactive for long.
Other channels cover the content but GorillaPhysics will help you get the grade 9 or that A* at A Level.
Also, if you like GorillaPhysics and want to help me shape and expand my channel and resources, why not join my Patreon community and become part of Gary’s squad:
Student Amazon Prime! Free prime for six months and then half price from then on!
This would have been so useful as a student to get next day delivery on so many essentials, but also for the music, and amazon video you get included in prime as well. You might as well really! And you say thanks to GorillaPhysics as I get a small bounty when you use my link!
You can now support GorillaPhysics by buying your next educational purchase from Amazon at my store:
At Gorilla Physics we’re all about you understanding more, so you get more confident, then enjoy Physics more and then you’ll do better in your GCSE and A Level Physics exams.
Buy my book to help you memorise all the equations for GCSE Physics or Combined Science, for AQA, OCR A and B, Edexcel and Eduqas exam boards.
You can have the kindle edition for free on your phone with a free trial of kindle unlimited:
