Tijdens dit verval komt er �- en y-straling vrij. De �-straling vernietigt de kankercellen. y-Straling heeft een veel langere dracht dan �-straling en wordt in aanzienlijk mindere mate door het lichaam geabsorbeerd, en kan daarom buiten het lichaam worden waargenomen.

Range (particle radiation)

In passing through matter, charged particles ionize and thus lose energy in many steps, until their energy is (almost) zero. The distance to this point is called the range of the particle. The range depends on the type of particle, on its initial energy and on the material through which it passes.


Dracht in de kernfysica, ook wel indringdiepte, is de afstand/weg die een deeltje/straling kan afleggen in een stof.

Some additional info:

Gamma Rays in Matter

Gamma attenuation :

The exponential attenuation of a narrow beam of gamma rays passing through an homogenous layer of material is characterized by an attenuation coefficient. The higher this coefficient, the faster is the attenuation. The attenuation coefficient is a measure of the interaction probability (called cross-section) of the gamma rays with the matter or the target. It is obtained by summing the contributions of the three effects: the photoelectric effect, the Compton effect, and (to a lesser degree) pair-production.

There is usually a significant probability that gamma rays travel a relatively great distance without being involved in any interaction. As a result, gamma radiation is both more penetrating and more difficult to stop than either alpha or beta. In laboratories and near accelerators, the custom is to use thick lead screens – a cheap and effective material - as gamma rays are more easily absorbed by heavier nuclei.

Alternatively, you could use (much larger) 'penetration depth' if you feel this suits your context better.
