Dose rate measurement through MCNP

AI Thread Summary
To calculate dose rate (Gy/h or rad/h) from a point source using MCNP, the F6 tally provides results in MeV/g, which can be converted to Gray using the FM card. To determine the dose rate, multiply the dose in Gray by the number of particles emitted per second. This approach allows for the conversion of the energy deposited per unit mass into a rate over time. Understanding the relationship between energy, dose, and particle emission is crucial for accurate calculations. This method effectively translates MCNP results into practical dose rate measurements.

I am interested to calculate dose rate (gy/h, rad/h) from a point source at a certain distance through MCNP. If I use F6 tally it will give answer in Mev/g which can be converted to Gray or rad by using FM card, but I don't know how can I find dose rate like rad/h or g/h.?

Hi,
1 Gy = 1 J/kg
1 eV = 1.6022E-19 J
hope it's help

I know to convert F6 tally (Mev/g) to dose (Gray) but how to find dose rate i.e Gray/hour from MCNP ?
 
mcnp gives the result for one particle. Simply multiply by the number of particles emitted per second
 
Ok thanks
 
Hello, I'm currently trying to compare theoretical results with an MCNP simulation. I'm using two discrete sets of data, intensity (probability) and linear attenuation coefficient, both functions of energy, to produce an attenuated energy spectrum after x-rays have passed through a thin layer of lead. I've been running through the calculations and I'm getting a higher average attenuated energy (~74 keV) than initial average energy (~33 keV). My guess is I'm doing something wrong somewhere...
