Possible candidate elements to be employed as converters for neutron detection.

Species	Cross Section [b]	Comment
157Gd	≈254,000	too many gammas (and toxic) [26,27]
113Cd	≈20,000	too many gammas (and toxic) [28,29]
3He	5333	expensive, being replaced in neutron detection applications, non-natural, produced in military reactors [30]
10B	3837	expensive, produces low energy alpha and 7Li particles but also gamma rays [31,32,33]
6Li	940	cheaper, easily deposited (6LiF), produces high-energy triton and alpha particles and no gamma rays [33,34]
235U	≈583	dangerous strategic material, radioactive, subject to radiation protection restrictions [33]
