$^{67}$ Cu produced by the $^{68}$ Zn() $^{67}$ Cu reaction was used for the first time to determine the biodistribution of $^{67}$ CuCl $_{2}$ in colorectal tumor-bearing mice. High uptake of $^{67}$ Cu was observed in the tumor as well as in the liver and kidney which are the major organs for copper metabolism. The result showing $^{67}$ Cu accumulation in the tumor suggests that $^{67}$ CuCl $_{2}$ can be a potential radionuclide agent for cancer radiotherapy. It would also encourage further studies on the therapeutic effect in small animals using an increased dose of $^{67}$ Cu produced by the $^{68}$ Zn() $^{67}$ Cu reaction using intense neutrons available at present.

This paper is written as one of the series on a news paper relevant to the Gunma Chemistry Exhibition to be held in commemoration of the 125th anniversary of the Chemical Society of Japan, telling readers that the origin of chemical elements is related to the radiation. As an example, K-40 is chosen for description of the fact that there exist natural radioactive elements. It is also mentioned that the origin of K-40 is ascribable to stars in the universe.

So far, samples have been taken by both Japan Government and the International Atomic Energy Agency (IAEA) from the feed accounting tank of the Reprocessing Plant. Upon transporting the samples, one A-type transport container per batch sample has been required. To simplify the transport of samples, the resin bead technique requiring the trace amounts of samples (several mg for uranium and for plutonium) has been developed with the Oak Ridge National Laboratory, USA being the center. This technique was introduced into the Power Reactor and Nuclear Fuel Development Corporation (PNC) as part of the TASTEX project, and then has been incorporated into the JASPAS project as one of the joint researches between the PNC and the IAEA, in which the PNC has played a leading role. Up to now, joint experiments have been performed seven times, and the resin bead technique may have reached a certain technical level with a few technical problems. In these joint experiments, the PNC prepared and transported samples, whereas the IAEA analysed them. In addition, the PNC has investigated the resin bead technique independently. As mentioned above, the most outstanding merit of the resin bead technique lies in the simplified transport of samples. The technique is also provided with another merit by which uranium and plutonium can be measured without separating them from each other, leading to the necessity of research and development of it on the part of the Reprocessing Plant. This paper describes the results of investigation on the measurement technique of uranium and plutonium by means of the resin bead technique, together with the results from the 3rd to 7th PNC-IAEA joint experiments.
