Safe distance calculation for X-ray

[harish prince]

 

Dear All,

 

I have got a point to be discussed in our group.

 

We all know how to calculate the safe distance or Cordon off area for Gamma.

 

But how are they calculating for X-ray...........????????????????

 

Waiting for ur replies

Arey Iam asking about the calculation.

 

here we will give 15 mts for 300Kv source.

 

I just want to know abt the calculation part. I'll try to find it referring some books.

Dear all..

According to IAEA  safe distance is @0.75 mR....for X-ray it is to best by choosing surveymeter,......

In the equipment specifications it is given that "Radiation leakage at 1m from the focal spot is < 10mSv/hr above 200Kv".

 

Can we use this value as RHM while calculating safe distance.

 

Or should we consider this as the radiation intensity at 1 mt for the 300Kv source....?

that is leakage radiation not mR..

we need to calculate mR @ 1 meter then we will apply insq. law.....
