➡️ LESSON DESCRIPTION: This lesson’s objectives are to define exposure and air KERMA and to differentiate between measurements in air vs. measurements in tissue. This lesson also explains how exposure is measured and the general relationship between exposure and prime exposure factors. This lesson also explains how air KERMA is measured and the general relationship between air KERMA and prime exposure factors. This lesson also explains how air KERMA and exposure are used in healthcare as well as compares and contrasts air KERMA and exposure.

You man, have gained a trophy with these videos. You are awesome at explaining such comprehensive topics like these. THANK YOU!

[@magimak4601]

Thank you so much sir.....explain more topics about radiology

[@Throwing_Photons]

This is was incredibly helpful differentiating exposure and Air Kerma! Thank you so much!

[@socheatpos5383]

Much thanks

[@shakhawansalih5601]

Very nice thanks

[@user-ub2wu8tl5x]

I enjoy and perfectly learn

As kvp increses energy of photon in x ray beam increses but number of photons will be unaltered

[@drrajeevdahiwal1856]

Yes absolutely correct but practically this will increase actual useful number of photons (Beam hardening) so apparently you can say increasing Kvp resulted in increase in useful number of photons but actual total number of photons produced will remain the same.
