An overview of the undergraduate chemistry programs of different universities across the world shows clearly that nuclear chemistry education doesn’t have a permanent status in chemistry curricula like classical sub-branches of chemistry which means like organic, inorganic, analytical, physical, and biochemistry, and this verifies the existence of serious educational problems in nuclear chemistry across the world. The challenges faced by professionals in this field have been voiced at different meetings and scientific platforms and a number of works and reports were appeared [1] [2] [3] [4] [5] . In parallel of these, in this examination study, the present status of nuclear chemistry education in different universities and countries was examined and evaluated.

As it is well known, several worldwide ranking systems for universities are operated and top world universities are scored [6] [7] . Surely, these ranking and scoring lists may be discussable; but, the universities that have high ranking scores and find places in the top levels of these lists are, in general, well known, prestigious, favored and successful universities, and the universities are in competition to climb to the top levels in these lists. For the examination of the present status of nuclear chemistry education in different universities and countries, undergraduate chemistry programs of top 50 universities and the number one university in 50 different countries were carefully investigated. In addition, about 35 universities were chosen to be remarkable examples for nuclear chemistry education in different countries.

Before starting the evaluation of the status of nuclear chemistry education, first of all, nuclear chemistry should be correctly defined and its place in chemistry education should be correctly determined. If it is not done, the educational problems in nuclear chemistry could not be correctly investigated and the remedies could not be correctly determined.

As it can easily be observed from the chemistry programs of the majority of chemistry departments in different universities worldwide, the classical branches of chemistry generally consist of organic, inorganic, analytical, physical, and biochemistry sub- branches as represented in Figure 1.

This reflects surely the historical development of chemistry; but, rapid development of chemical knowledge and its applications in science and technology have created too many fine subbranches in about last 50 years such as electrochemistry, polymer chemistry, medicinal chemistry, geochemistry, coordination chemistry, computational chemistry, environmental chemistry, quantum chemistry, theoretical chemistry, pharmaceutical chemistry, photochemistry, solid-state chemistry, etc. Of course, radiochemistry, radiation chemistry, radioanalytical chemistry, radiopharmaceutical chemistry, etc. should also be included in this list as other fine sub-branches of chemistry.

Here, it should be asked: “Where is the place of nuclear chemistry in the main

branch of Chemistry?” and a correct answer for this very critical question for nuclear chemistry must find. First of all, we must understand, why the main classical chemistry branches are considered to consist of five branches that is organic, inorganic, analytical, physical, and biochemistry? When basic methods and the main considerations of these sub-branches of chemistry are carefully examined, the answer to this question can easily be understood. It mean that the basic methods and the main considerations of these sub-branches of chemistry are completely different from each other; but, in spite of the appearance of new fine sub-branches that were indicated above, the main sub-branches of chemistry did not change. Why? Because, the basic methods and main considerations used by these new fine sub-branches can be collected, in principle, under these five sub-branches of chemistry.

As is well known, with the discovery of a radioactive material by Henry Becquerel in 1896 and then, some others by Marie Curie, and also nuclear radiation, chemistry envisaged using new methods and considerations for studying the chemistry of radioactive materials and related nuclear radiation. Following this discovery, the term “Radiochemistry” was introduced as the first term related to the chemistry of radioactive materials in the chemistry literature.

In the following years, according to the new applications of radioactive materials and nuclear radiation in different fields of science and technology, additional new terms were introduced into the literature of chemistry such as nuclear chemistry, radiation chemistry, radioanalytical chemistry, radiopharmaceutical chemistry, nuclear and radiochemistry, etc. Now, it should be interrogated, if all these fine sub-branches of chemistry that are related to the chemistry of radioactive materials and nuclear radiation, can be collected under the five classical sub-branches of chemistry, like all other fine sub-branches indicated above, or not? The answer is simple and clear: No! Because, all these fine sub-branches have completely different methods and considerations for studying of the chemistry related to radioactive materials and nuclear radiation than that of the five classical sub-branches of chemistry.

For this reason, all these fine sub-branches of chemistry that are related to the chemistry of radioactive materials and nuclear radiation should be collected under a special category and introduced into the main sub-branches of chemistry. What term can be used as an umbrella for all of these fine sub-branches of chemistry related to radioactive materials and nuclear radiation?

Looking at the famous text books published in approximately the last 60 years in this field of chemistry, which is related to the chemistry of radioactive materials and nuclear radiation and their applications in science and technology will surely help to find the term as umbrella.

In 1949 a textbook was published by Gerhard Friedlander and Joseph W. Kennedy with the title “Introduction to Radiochemistry” [8] .

In 1957, another textbook in French was published by Moise Häissinsky, a French author, with the title “La Chimie Nucléaire et ses Applications”, including all knowledge related to radioactive materials and nuclear radiation up that date. This book was later published in English with the title “Nuclear Chemistry and its Applications” in 1964 [9] .

In 1966, Gerhard Friedlander and Joseph W. Kennedy have published the second edition of their textbook that include the name of Julian Malcolm Miller as the third author with the title “Nuclear and Radiochemistry”, including similarly updated knowledge in this field [10] . Of course, this title resulted in an important question: Are nuclear chemistry and radiochemistry different fine sub-branches of chemistry? Also, does it cover other fine sub-branches such as radiation chemistry, radioanalytical chemistry, radiopharmaceutical chemistry, etc, or not? It must find correct answers to these questions.

In 1980, Gregory Choppin and Jan Rydberg published their famous textbook with the title “Nuclear Chemistry (Theory and Applications)” that included nearly all topics related to the fine sub-branches mentioned above, which are related to the chemistry of radioactive materials and nuclear radiation and their scientific and technological applications as specific chapters and/or sub-chapters [11] . It should also be noted that these authors wrote in the preface of their textbook, seemingly to obscure the confusion between the main types of this branch of chemistry that “There is no universally accepted definition for the term nuclear chemistry”. At the same time, it is interesting that later editions of this textbook appeared with the title “Radiochemistry and Nuclear Chemistry” without considerably changing the contents of the main topics in the first edition [12] [13] [14] .

In 2003, A handbook series consisted of five volumes published in English by Atilla Vértes, Sándor Nagy, and Zoltán Klencsár with the title “Nuclear Chemistry” and each volume specified different topics. The sixth volume was later added to this series [15] .

Some other textbooks published with different titles in this period of time from the 1960’s to today are listed in Table 1. As it is seen from this table, the majority of these textbooks are titled as “Nuclear Chemistry” and a few books have “Radiochemistry” titles, while only a book has the title “Nuclear and Radiochemistry”.

It is also interesting to note that a journal with the title of “Radioanalytical Chemistry” was founded in January 1968 by the famous Hungarian scientist, Tibor Braun. Surely, this was a great step for analytical chemists who work with radioactive

materials and nuclear radiation to obtain a good platform for publication of their research reports. According to the rapid development of this branch of chemistry, the title of that journal was updated in 1984, 16 years after the founding, to the “Journal of Radioanalytical and Nuclear Chemistry”. Of course, this title has created a similar question: Are radioanalytical chemistry and nuclear chemistry different fine sub- branches of chemistry, or not?

In this period of time, also new terms appeared and are used in this field of chemistry such as radiation chemistry, radiopharmaceutical chemistry, environmental radiochemistry, etc.

In 1999, the organizers of the International Nuclear Chemistry Forum, distributed an inquiry to many scientists who were directly or indirectly related to the chemistry of nuclear materials and nuclear radiation and their applications in which the following question was included: “Do you consider that nuclear chemistry and radiochemistry are different fields?” Out of about 250 ansvers 35% answered Yes and 65% answered No.

This story clearly verifies that a confusion of terminology or at least, turbulence exist in this branch of chemistry about the use of these terms.

Briefly, starting from the textbooks of Moise Häissinsky, the first edition of Gregory Choppin et al., the six volumes of Atilla Vértes et al., and others, nuclear chemistry should be considered as the title of the sixth main sub-branch of chemistry as is considered in the web site given as ref. [16] that covers all chemical studies related to radioactive materials and nuclear radiation including fine sub-branches such as radiochemistry, radiation chemistry, radioanalytical chemistry, radiopharmaceutical chemistry, environmental radiochemistry, and others as represented in Figure 2 and Figure 3.

The international ranking system for universities as the success reference of universities was first considered for examination of the status of nuclear chemistry education across the world.

This short overview of nuclear chemistry education programs has reached some important conclusions:

1) The umbrella role of nuclear chemistry should be strongly supported everywhere;

2) Nuclear chemistry should be emphasized as the sixth main sub-branch of chemistry;

3) The overview of nuclear chemistry education in universities across the world has clearly indicated that nuclear chemistry education has not yet achieved a classical status in chemistry curricula worldwide like organic, analytical, inorganic, physical, and biochemistry; but, all undergraduate chemistry programs of universities across the world should cover at least one nuclear chemistry course with some laboratory experiments, like in the case of other main sub-branches of chemistry;

4) It is evident that the majority of active chemistry staff surely does not have enough knowledge of today’s importance of nuclear chemistry and its scientific and technological applications, which results in a huge lack of nuclear chemistry education in the formulation of chemistry curricula;

5) This present status prevents the education of new staffs in nuclear chemistry and so, this creates a vicious circle for the subject;

6) The universities having remarkable nuclear chemistry courses which were identified can be attributed to the personal efforts of some well-educated staff in nuclear chemistry and this does not guarantee that the same status will continue in the future in their universities after their retirements and for this reason, it will be evident that as notified by Gregory Choppin “The need for radiochemists (he meant surely nuclear chemists) must grow; but in most countries, including the US, there will soon be no professors to train them!”;

7) Today’s active nuclear chemistry staff should understand that they have been charged with a very important mission for the future status of nuclear chemistry and that they need to be much more active and try to help other chemistry staff in their universities to understand that nuclear chemistry education should have a permanent place in chemistry curricula without depending on temporary personnel efforts and activities;

8) Nuclear chemistry staff should communicate with all national or international scientific organizations to spread more understanding of the important role of nuclear chemistry in scientific and technological applications required for future human life;

9) The number of civil national and international organizations such as the Inter- national Nuclear Chemistry Socciety (INCS) and the Radiochemistry Society in the US, etc. should be increased;

10) A master program for nuclear chemistry in undergraduate education needs to be formulated and it should be recommended for introduction into all chemistry curricula in various universities across the world. This would help to create more interest in the field of nuclear chemistry among the younger generation.
