5:30 Lead cavity And this lead cavity used because it do not react with the radioactive substance which was placed inside it.

[@krishnachourasiya5454]

5:53 radioactive sample placed in lead cavity because lead is very less reactive metal so it can not react with the sample.

[@krishnachourasiya5454]

5:35 Lead cavity

[@PrishaRai-sg6uh]

Radioactive sample are kept in lead cavaty due to not to reacte with radioactive sample as they are very less reactive metal

[@MohammedYusha]

Sir alpha aprticles ko lead cavity mai rakha gya tha kyunki woh less reactive h towards radioactive elements

[@FutureNostalgia5ever]

Lead Cavity so that alpha particles do not react with the materials it is paced indside. Lead does not react with radioactive substance.

[@NikitaVerma-x5e]

Thank you sir for this wonderful explanation 😊😊

[@Gaurikasare-kd5qw]

Sir notes kaise download kare

[@simple.decoding]

badhiyaa sirrr ms=asttt

[@nikita-j4g]

Because it doesn't react with the radioactive substances which was placed inside it

[@comedyclub9939]

Radioactive placed in lead cavity because lead cavity do not react with radioactive ❤😊

[@sonamparween5671]

Because lead do not easily react with alpha particles

[@praduam114]

Pb, bez it doesn't react with alpha partical

[@premkumarsingh1621]

Because radioactive sample does not react with the lead cavity

[@Deepak_Mishra210]

Becoz of rxn

[@premkumarsingh1621]

Radioactive sample is placed in lead cavity😊

[@nikita-j4g]

Lead cavity

[@Shreyash9565]

5:37 Lead cavity 🙋‍♀️

[@Shreyash9565]

The reason behind this is lead does not react radioactive sample 🙋‍♀️

[@anvitanvitsharma9275]

Lead cavity mai rakha tha sir
