Radiation in Glasgow
You may have heard that radiation from Fukushima has been detected in Glasgow and in Oxford. Here is the BBC report. Read the article yourself and decide whether you are in imminent danger.

The Assessment
Half life
Equations
Nuclear Reactor
Model of the Atom
Alpha, Beta and Gamma Properties.
You have to get 12 out of 18 to pass.
The time allowed for the assessment is 25 minutes.
After the assessment we will start Science Practical Skills - here's hoping its a sunny day!

BBC Bitesize
BBC Bitesize has a nice description of nuclear fission. Note that you do not have to know about 'fusion'.
How to answer assessment questions
It is important to read the questions carefully and answer the question.
If the question is 'What is a beta particle?' the answer would be 'an electron'. Everything else is 'icing on the cake'. i.e they describe it - it has a small mass, it comes from the nucleus when a neutron changes to an electron + proton, it has a negative charge. These are all things things which describe the beta particle - they don't say what it is. There is a subtle difference.
The key information - its an electron!!
Example
What is a camera? Ans: Its is a device for taking photographs.
Wrong answer - It weighs about 90 g, sometimes its black or silver, it has a lens, it might be digital and I got one for Christmas.
Get the idea?

Help please
I have quizes to help you with your studying. Can you click on the link and let me know if the crossword works.
Leave a comment and state whether you are using your home computer or a college computer. Thanks. Carol

Nuclear Weapons (for info only)
Nuclear weapons are noy really in the course but some awareness is no bad thing.

Radiation Lab Download
Radiation Lab can be downloaded from Visual Simulations. You will need to register but it is free. Instructions for using the simulation are the last post. Let me know how you get on by leaving a comment.

Dounreay Clean Up
When particles of plutonium were washed up on a beach the clean-up began. Article in the Guardian.

Background Radiation Video
This video is from the Teachers' Domain. It is American but is still very relevant.
You can play it by clicking on the title or clicking here. The units they use are not the same as we use now.

Background Radiation
Here is a link to a video which is for interest only.
Questions
What is the gas which is seeping into houses?
What does the unit 'becquerel' measure?
What is the biggest cause of lung cancer in Ireland?

Day 2 Ionising Radiations
We started of by summarising the model of the atom and alpha, beta and gamma radiation.I was impressed by how many of you had been in the blog and the Andy Darvel physics site.
We then used Flash Learning's Interactive Intermediate 2 Physics. This covers the whole course and is in the library.
After break we migrated to an IT romm to do the simulated experiments for the range of alpha, beta and gamma in air and the absorption of alpha beta and gamma by paper, aluminium and lead.
I got the impression that by the end most of you understood it.
A couple of you copied the simulations onto your USB stick - good idea. It would be a great help if all of you had a USB stick for next week.
I enjoyed the lesson today.

Day 1 - Intro to the Course
Introduction
Terminology
What is radioactivity?
Background Radiation
Half Life
Video (if it works) about 'Barney the Horse' and another horse called 'Just another Gamble'. Although the medical treatments are on animals the same treatments are used on humans.
Introduction to your website.
The following links are interesting.
X-Ray safety Please note that this is a pdf and can take a while to load if you are not using Broadband. College computers should be OK.
Nuclear Medicine
In the last few years imaging techniques have improved enormously. The X-ray is now only one of many techniques. The equipment is expensive and radiographers are in short supply.
The link below has links to a site with many more links. You could spend a week here!
