Hello: Today i did an experiment in my physics class about radioactive isotopes, we tested cobalt-60 and Strontium-90. We got readings for Sr-90 of 176 counts without protectionand 76 with lead protection. What im asking in regards to this is the possibily of getting cancer or perhaps something else in my body, im a little worried that this exposure is dangerous for my health in the long run. is there a possibility of me getting cancer?
@gcmarcal Hahahahaha. I had to ask a friend what Optimus Prime is... how bad is that :/
I think I must have pronounced it too Aussie :). Beta decay can *really* happen 3 way. The first is when a neutron rich nucleus emits a high speed electron (a negative electron can also be called a 'negatron') and also emits an antineutrino. This is usually what beta decay refers to, but to me more technical, it is referred to as negatron emission.
@gcmarcal Then, there's positron emission. Which is where a neutron deficient nucleus, changes a proton into a neutron (the opposite from negatron) and emits a 'positron' - a positive electron, which is really the anti-particle of an electron. Positrons are annihilated when they collide with normal matter (not anti-matter) to give gamma radiation. Since everything is made of matter on Earth, they are annihilated almost immediately!
@gcmarcal And the third which I didn't mention is electron capture, where an ordinary *atomic* electron is captured by the nucleus, and then a proton is changed into a neutron and you get the neutrino emission again. BUT, you also get an electron missing, which is very quickly filled in by another electron, and in the process gives off an x-ray. Sometimes, an outer atomic electron is also emitted (and Auger electron).
My physics teacher is killing me >.< For real. And you know what? This monday I'll be asked about radioactivity and I'll answer it perfectly because this video helped me to understand while the teacher didn't. THANKS!!!
@zweefseef Oh. That means microsieverts per hour. The accumulated dose- how much dose you get in total is measures in sieverts. It's like the odometer in a car telling you your milage all up. Except the dose is such a small fraction of a sievert, the annual dose is just over one millisievert- 100 microsieverts. One millisievert is 1000th of sievert. Micro is 1000000th.
@zweefseef However. Dose rate is also needed, measured in uSv/h. In otherwords how much dose you get over a period of time. Exactly like a speedometer on a car, except with radiation, you want dose and dose rate to be kept to a minimum.
If you've seen cpm or cps, that's to assess contamination. Not used to monitor dosage at all. Purely how radioactive something is. Usually involv^ing a probe separate from the meter. Whereas anything measuring in uSv/h is a dose rate meter.
@zweefseef Dose rate meters are used often at a distance from the source to where the body is as exposure decreases with increased distance.
Last of all, anything measuring in uSv or mSv is a dosimeter. Sometimes a film badge, sometimes electronic. Used to monitor the all up dose. Film badges would be useless in Fukoshima as they dont deliver results instantaneously. Something imperative at a nuclear disaster.
I hope that kinda helped. Let me know if you want more info.
@zweefseef Hey! I went to a nuclear research centre two week ago, and guess what. If the dose rate was even 1uSv/h, I couldn't enter the experimental area! That is the limit for the general public in Australia.
I made a mistake earlier. The backround dose rate (at least in this part of the world, is much less than 1uSv/h). I'm not too sure exactly what it is, but it shouldn't even be one.

@galvanchristian do you think it's too complicated? I want anybody to be able to find it agreeable to watch, so any feedback at how I could improve would be really great. Any ideas?
I found your video because I wanted to know more about the nuclear disaster in Japan because of the earthquake and tsunami. I see you uploaded this Christmas day of last year. Who knew then that it would be so timely now. Good stuff.
@Tazigay When it's all over, I will probably make a video on it. I want to get into heavy reactor theory. This was just a very basic... I had to cover it before I go on about something else.
@sxs0nar There is a formula used to show this, called the semi-empirical mass formula of which is based on the liquid drop model- which takes into consideration lots of different energies within the nucleus to be able to predict the total binding energy. Since particle radiation is emitted from the nucleus- yes, this could be thought of in that way, except not in the case of gamma radiation, as it involves no particles. This can be used to predict how a nucleus will decay- the decay mode.
@sxs0nar Well! This is one model out of two popular ones used to predict binding energy- the energy that's required to hold the nucleus together. : the liquid-drop model- which is used more when performing calculations which involve the nucleus as a whole, and the shell model- which has a more individual focus on nuclei. The liquid-drop model is very effective showing the nucleus can behave like a drop of a liquid- showing why the nucleus has a spherical shape.
I am so glad you made this. It was so boring when my teachers explained radioactivity in school. It finally makes sense to me now! I'm curious though. What does it mean for nuclei to be "excited"???

@joethursdays hello joe! thanks for that... I'm glad you thought it was awesome. Your American idiom confuses me... what's a swagger? What happens if it's hella? Should I be concerned??
@AlbertAldehyde Hahaha, well, as Keri Hilson put it: "Swagger ain't something you can wear on your neck; you can buy a gold chain but you can't buy respect." So having hella swagger is good ;)
I thought i knew a lot about radioactivity but ur detailed information enlightened me on a few things as my area of expertise isnt atomic physics thanks

he got well within the danger zone (20 km is the dangerzone, he got around 1,5 km)
but he uses a thing wich i can't understand and that is : uSv/h (that 'u' like the utorrent one) i don't understand that part
