As doses de radiação ionizante para os trabalhadores no transporte de material radioativo devem ser tão pequenas quanto razoavelmente exequível. As doses médias dos motoristas e carregadores amostrados neste trabalho devem ser diminuídas. A demonstração do controle das doses em veículo rodoviário com material radioativo, requisitada pelo regulamento brasileiro atual, norma CNEN NE 5.01, é apresentada em formulário próprio com valores de exposição obtidos em posições de ocupação regular de indivíduos do público e de trabalhadores, mesmo quando se expede veículo sem a necessidade de uso exclusivo (∑ IT 50). Este trabalho mostra, por meio de pesquisa bibliográfica, elaboração de modelos e pesquisa de campo, que esta demonstração do controle com a obtenção dos valores de exposição nesta situação, para um método de controle melhor, deve ser realizada pela apresentação do registro do acúmulo de cargas, limitado (∑ IT 50), a fim de evitar a obtenção destas medidas, para que haja padronização com regulamentos estrangeiros e para que os custos e os tempos, importantes para expedição de radiofármacos com meia-vida curta, e também as atuais doses laborais dos técnicos de radioproteção sejam todos diminuídos. Os valores de exposição dos parâmetros utilizados com esse método são menores do que seus limites regulamentares. Para contribuir com essas finalidades devem ser apresentadas pelo regulamento brasileiro atualizado as distâncias de segregação entre as cargas e as cabines dos veículos. / The radiation doses to workers in the transport of radioactive material should be as low as reasonably achievable. The average doses of drivers and loaders, sampled in this thesis should be decreased. The demonstration of doses control in a road vehicle with radioactive material required by the current Brazilian regulation, CNEN NE 5.01 should be written in its own printed form with exposure values obtained in normally occupied positions from workers and members of the public, even when the consignment does not need \"exclusive use\" (∑ IT 50). Through bibliographic research, modeling and field research, this research work shows that this demonstration of the control should be done by writing the registration accumulation of load, limited (∑ IT 50), also in the own printed form. It is for a better control method, in order to avoid the use of measuring equipment, to build standardization with foreign regulations, to the current occupational doses of radioprotection technicians, the costs and time, (important for consignment with radiopharmaceuticals short half-life) would be all smaller. Exposure values of the parameters used with this method are smaller than regulatory limits. The segregation distances between loads and the cabins of vehicles shall be showed by Brazilian regulation updated to contribute to these aims.

Rapid growth of cities has become a trend in most countries, this is caused by urbanisation wherein people move from the rural areas to the urban areas in search of employment. It goes without saying that such population needs housing. However, it is unusual to find land for housing in an already crowded place. Therefore, to curb this shortage in housing, countries like South Africa have resorted to adoption of fragmented property holding in and around the cities. Thus, in an attempt to curtail housing shortages in the urban area as well as land shortage, communal property schemes were adopted together with their governing legislation namely, Sectional Titles Act 95 of 1986, Share Blocks Act 59 of 1980 and Property Time-sharing Control Act 75 of 1983 to name a few. Likewise, Maseru, the capital city of Lesotho is also experiencing rapid growth in population. Hence, with the introduction of Lesotho’s Sectional Titles Bill 2013 came a ray of hope that the land and housing shortage in Maseru would be addressed. With this in mind, this suggested that the Government of Lesotho together with all concerned stakeholders thought it necessary to address this problem through the 2013 Bill which, for the most part follows the South African Sectional Titles Act of 1986. It is for this reason that this study was embarked on to show other forms of property holding akin to sectional titles as well as their regulation, which can all be used to eliminate housing shortages in Lesotho. / LLM (Estate Law), North-West University, Potchefstroom Campus, 2015
