Could anybody advise me, where i can read about how to calculate radiation dose from neutron source for human body.
Excuse me for a second similar topic.

www.unscear.org is probably the best place to find the latest recommendations from the UN and the IAEA.
Cheers
Excuse mefatra2 said:Hi there,
What kind of dose are you hoping to calculate: the air-kerma, the absorbed dose, the equivalent dose, the effective dose, the ambient dose H*(10), the ambient dose H*(0.07)? Then, will your neutron source give a homogeneous field, which body part will be exposed to it, what is the energy range of the neutron source, are also question that you must answer before even trying to make any kind of calculation. Just saying that you want to find a formula on how to calculate the dose for a neutron source for a human body is not like backing cookies: there is not one recipe for it.
You can start by looking at the unscear website. The IAEA and the ICRP website are also very good place to find information on the latest on radiation exposure.
Cheers
The radiation dose from a neutron source can be calculated by multiplying the neutron flux by the neutron fluence rate. The neutron flux measures the number of neutrons that pass through a given area in a certain amount of time, while the neutron fluence rate measures the number of neutrons that pass through a given area over a certain period of time.
The equation for calculating radiation dose from a neutron source is D = Φ x Φn x Σen x t, where D is the dose, Φ is the neutron flux, Φn is the neutron fluence rate, Σen is the average energy per neutron, and t is the exposure time.
The neutron flux and neutron fluence rate can be measured using a neutron dosimeter, which is a device that detects and measures the number of neutrons passing through it. The dosimeter can be placed at different distances from the neutron source to determine the flux and fluence rate at various distances.
Yes, the radiation dose from a neutron source can be reduced by increasing the distance between the source and the individual, as the dose decreases exponentially with distance. Shielding materials such as lead or concrete can also be used to reduce the dose.
Yes, it is important to use proper protective equipment such as gloves, lab coats, and shielding materials when working with a neutron source. It is also important to follow safety protocols and regulations set by your institution or governing bodies when working with radioactive materials.
