RADIATION PROTECTION (AMENDEMENT) ACT 2014

An Act to control and regulate the import, export, manufacture, sale, disposal, transport, storage, possession and use of radioactive materials and irradiating apparatus, to make provision in relation to the non-proliferation of nuclear weapons, to establish a system for the imposition and maintenance of nuclear safeguards, and to implement the Convention on the Physical Protection of Nuclear Material, and to provide for matters connected therewith.

The Radiation Protection Act is administrated by the Radiation Protection and Nuclear Science Division (RPNSD) of the National Environment Agency (NEA).

​

Under this Act, there are 4 sets of Regulations:

  • Radiation Protection (Ionising Radiation) Radiation Regulations 2000

​

  • Radiation Protection (Non-Ionising Radiation) (Amendment) Regulations 2019

​

  • Radiation Protection (Transport of Radioactive Materials) Regulations 2000

​

  • Radiation Protection (Exemption for Transit, Transshipment and Carriage of Conveyance Equipment) Regulations 2014

Ionising Radiation Regulations

  • Anyone engaged in radiation work must have a license or be registered as a radiation worker and he should wear a personal monitoring device to monitor the amount of radiation received in the course of his work.

​

  • The licensee should ensure that each irradiating apparatus and each container of radioactive material is properly labelled with the radiation hazard logo.

​

  • Radioactive materials should be stored in a safe and secured place. Outside the defined area where the radioactive materials are stored, the radiation levels must not exceed 0.5 µSv/hr.

Non-Ionising Radiation Regulations

  • Concerns over the safety of microwave ovens, lasers and ultrasonic devices were increasingly being used in domestic, industrial, and medical applications.

​

  • Lasers that are used for the purpose of in vivo diagnostic, surgical, therapeutic laser irradiation of any part of the human body are classified as medical lasers under the Act.

​

  • With that, control over these potentially hazardous non-ionising radiation (NIR) devices is therefore necessary to ensure the safety of the people using such devices.

​

  • Licences are required for importing, exporting, manufacture, possession, use and sale of specified NIR apparatus.

​

  • All NIR apparatus should be manufactured, designed, and labelled so that the requirements on shielding, interlocks and warning devices are met.

​

  • Licences for medical diagnostic and surgical ultrasonic devices may be granted to qualified medical practitioners only.

Transport of Radioactive Materials Regulations

  • Aims to provide a uniform and adequate level of safety which is suitable for the inherent hazard presented by the transportation of radioactive material by land, sea and air.

​

  • Primary consideration is placed on:

  1. The safety features which are required to be built into the design of the package and requirements for testing the package design, thus minimising the need for any special actions during carriage

  2. Operational requirements for the implementation of, and compliance with the requirements of the Regulations for testing the package design, thus minimising the need for any special actions during carriage.

​

  • Any conveyance used for the transport of consumer products to the point of retail sale to a member of the public as an end user must meet the applicable requirements of the Regulations.

​

  • To minimise the possibility of radioactive material packages losing their containment integrity owing to the interaction of the package with other dangerous goods, they should be kept segregated from other dangerous cargo during transport or storage.

​

  • The Regulations are not intended to be applied to movements of radioactive material that forms an integral part of a means of transport, such as depleted uranium counterweights or tritium exit signs used in aircraft.

Exemption for Transit, Transshipment and Carriage of Conveyance Equipment Regulations

  • Exempts consignors from licensing requirements stipulated in the Radiation Protection Act for radioactive material and irradiating apparatus (excluding nuclear material) that are transited or transshipped through Singapore.

Radiation Licencing Fees.png

  • *N2 licence no longer required for industrial ultrasound apparatus with power output less than 1,200W

​

  • *Removal of requirement for N3 licence for medical and dentistry professionals if they have obtained the consent of the following persons to use a medical laser at a healthcare institution as per mentioned below:

  1. The individual in charge of that healthcare institution

  2. The licensee of the N2 licence granted in respect of that medical laser.

Medical Usage

  • Sufficient space available

​

  • Thickness of walls and doors to provide protection

​

  • Control panel must be outside with red lights on when radiation source is on

​

  • Automatically terminate after preset time or dose

​

  • Must be equipped with suitable radiation monitors or survey meters

​

  • Radiation accident:

    1. non-medical application - unplanned, uncontrolled high level of radiation occurs

    2. medical application - therapeutic treatment is delivered to the wrong patient or to the wrong tissue of any patient; or if the patient is treated with a dose or dose fractionation which differs by more than 10 per cent from the value prescribed by the radiologist in charge of the treatment; or if the wrong radiopharmaceutical is used
