av JO Lijenzin · 1996 — The radioactive source may be a whole reactor, the spent fuel annually The waste is divided in high-level (fission products FP) and Alpha (trans-Iead TL). For LWR the risk dominates in the order 90Sr, 241 Am, 24_ Am,
In this kind of RTG, the alpha decay from the radioisotope is also used in alpha-neutron reactions with a suitable element such as beryllium. This way a long-lived neutron source is produced. Because the system is working with a criticality close to but less than 1, i.e. K eff < 1, a subcritical multiplication is achieved which increases the neutron background and produces energy from fission
2017-03-09 · We're in the optimization phase of our game and we've gotten pointers towards transparency/alpha in textures/sprites being quite costly to render. So I've checked out the 'Alpha Source' setting on our Textures and tried to change it to 'None' from 'Input Texture Alpha'. The thing is, it seems to do nothing.

One reason for this may be that the activity, i.e. the alpha particle flux, of source 1 and 2 are 50 times higher than source 3.
241 Am], the isotope in smoke detectors) is one of the most widely available and affordable sources of alpha radiation. 241 Am has a half-life of 432 years, enabling longlived power and high energy density for sensors and - communications devices located in remote or harsh environments.

Abstract. The neutron energy distribution of the IRSN standard 241Am–Be(α,n) source was measured using a proton recoil liquid scintillator, BC501A, >1.65 MeV 2013-05-10 · Abstract: A new search for production of correlated e+e- pairs in the alpha decay of 241Am has been carried out deep underground at the Gran Sasso National Laboratory of the I.N.F.N. by using pairs of NaI(Tl) detectors of the DAMA/LIBRA set-up. The radioactive source in most smoke detectors is 241Am which (a) Write down its alpha decay equation and predict the product nucleus. (b) What is the initial source activity? (c) What would be the source’s activity after 40 years in operation? (d) How many 241Am, nuclei would have decayed in A new search for production of correlated pairs in the decay of (241)Am has been carried out deep underground at the Gran Sasso National Laboratory of the IN We have developed MICROMEGAS (MICRO MEsh GASeous) detectors for detecting a particles emitted from an 241Am standard source.
