(c) Radio-HPLC analysis of [sup.177]Lu-iPSMA obtained from a multidose lyophilized kit before injection to patients with high radiochemical purity (>99%).
The data from high-yield and radiochemical purity studies (>98%) and biodistribution studies showed that [sup.18]F-FP2OP PET has a significantly high heart uptake; the imaging showed a clear outline of the myocardium in a healthy Chinese miniswine [64].
To determine the Radiochemical purity of 99mTc-clarithromycin, the sample of 1 uL was spotted at ITLC silica gel strips (Gelman Laboratories) and developed using 0.5 M NaOH as the mobile phase.

However, the latter one was reevaluated by another research group (13) and the radiochemical purity value was higher than when using the standard procedure ([Al.sub.2][O.sub.3] Baker-Flex strip/ethanol), giving a false-positive purity value.
[[sup.123/125]I]-CLINME was eluted with a retention time k' = 14 min in a radiochemical yield of 74 [+ or -] 5% (n = 8) and 86 [+ or -] 8% (n = 4) for [[sup.123]I]and [[sup.125]I]-CLINME, respectively.
This required intense neutron irradiation at ORNL's High Flux Isotope Reactor, followed by chemical separation and purification at ORNL's Radiochemical Engineering Development Center.
Radiochemical purity tests were conducted for all the products showing more than 97% "in vitro" stability in all cases after 4 hours.
In the experience of the authors, the additional cost of a typical PET study in 6 to 10 patients including development of radiochemical synthesis methods, regulatory approvals, and data analysis can range between 0.5 [pounds sterling] and 1 million.
[sup.125]I-Sodium iodine, with the radiochemical purity >99.9%, was purchased from NEN Life Science Products, Amersham Inc.
Thanks to the effective methodology adopted, the radiochemical experiments were able to provide very important results in the studies of solar neutrinos, demonstrating unambiguously the discrepancy between the measured and predicted solar neutrino fluxes and triggering the subsequent vast theoretical and experimental investigations culminated in the proof of the oscillation effect in the solar neutrino sector.
The goal is to provide a broad and unified reference to all possible radiation-chemistry interactions for researchers and engineers in nuclear laboratories, nuclear electric plants, and radiochemical factories.
