i'll try it, thanks a lot

ok, what is peak area?peak intensity?efficiency of detector?branching ratio of the source? Peak centroid?and FWHM? How do they relate with the activity concentration of a nuclide at that peak?..i know my questions are plenty ,i just need your help!

i've been delaying the experiment because I've got no standard source, can i go on without it?

Thanks a lot, I'll get back to you when i start the analysis.

Thanks, I'll carry out the experiment tommorow, I do not have a source with known activity, is there no other way to caliberate without a source? And how does finding the activity depends on my set-up?

Ok, can you give me the explicit expression that bind this informations as a whole?- that will allow me compute the activity

Am currently doing an undergraduate project work on 'estimation of radiological risk pose by U-238, th-232 and K-40 in rock samples' . The instrument I'll use are NaI(TI) crystal for scintilation were the gamma rays from the source(my rock samples) interact with the crystal through photoelectric...

Aaron, thanks for the 1st class explanations. And Bobbywhy, your link is fantastic.

Using a Clamp-on meter, what is the importance of the recorded currents from the upriser cable?is there a normal current that you compare with the recorded current?what current level triggers load shedding?

it did,thanks

Thanks a lot,it helps,but you didn't mention the name of the fuse or is it truly 'j&p fuse' as mentioned by the technician?.In addition to that,what's the difference between star connection and delta connection?,where does the neutral phase originate from in a transformer and what role does it play?

I'm an undergraduate studying physics & I live in a place that is about 15m away from a 33kva distribution substation,i already know the transformer work based on the principle of faraday law of EM induction,the feeder pillar distributes electricity in units,the fuses in the feeder pillar...
