What Experiments Can Demonstrate Gamma Rays in the Classroom?

AI Thread Summary
Gamma rays are high-frequency radiation that can be dangerous and challenging to produce safely in a classroom setting. Key topics for a presentation include the definition of gamma rays, their production, uses, health effects, and the importance of shielding. Demonstrating gamma rays requires appropriate safety measures, and the availability of a weak source is crucial for any experiment. The discussion emphasizes the need for caution and proper equipment when considering experiments involving gamma radiation. Overall, safety and educational value are paramount in any proposed demonstration.

I need to do a presentation to teach the rest of my class about Gamma rays. We need to do some sort of experiment to demonstrate Gamma Rays. Any ideas?

Hi,
I can give you some idea:
You can present:
1. What is gamma ray.
2. How it is produced.
3. Uses and health effects.
4. Shielding of gamma ray.
5. About experiment-I really have no idea. Demonstrating gamma rays requires good shielding.
 
Thank I have all the ones except 5
 
What do you have available? Gamma radiation is high-frequency radiation that a) is dangerous to produce and b) relatively difficult to produce. I don't know how much your professor/teacher wants you exposing your class to harmful radiation.
 
He said he has some weak source that can produced gamma rays I'm just trying to find out what that is by emailing him this weekend

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
