Elements quantified by neutron activation analysis

 

Neutron activation analysis (NAA) is used to determine concentrations in a sample. It offers a highly reliable measurement technique fully traceable to primary SI-standards.

 

Short Irradiation

 
A short irradiation of up to 15 minutes may allow the concentration of the following elements to be determined:
 
Al, Ca, Cl, Cu, Dy, I, In, Mg, Mn, Na, Rh, S, Ti, V.
 
Long Irradiation
 
A long irradiation of up to 20 hours may enable the analysis of:
 
Ag, As, Au, Ba, Br, Ca, Ce, Cd, Co, Cr, Cs, Er, Eu, Fe, Ga, Ge, Gd, Hf, Hg, Ho, In, Ir, K, La, Lu, Mo, Nb, Nd, Os, Pd, Pr, Pt, Rb, Re, Ru, Sb, Sc, Se, Sm, Sn, Sr, Ta, Tb, Te, Th,Tm, U, W, Yb, Zn, Zr.
 
Reporting times will depend on reactor scheduling but typically reports may be issued within a month of receipt of samples for short irradiations and within two months where long irradiations are required.

Reporting times
 
Reporting times will depend on reactor scheduling but typically reports may be issued within a month of receipt of samples for short irradiations and within two months where long irradiations are required.
 
Typical sample sizes are from 50 to 150 mg for both short and long irradiations. Larger samples may be used if the bulk matrix material does not activate strongly.
